2-METHYL-AP-237 hydrochloride in precision-compressed 20 mg pellet format delivers unmatched dosing accuracy and batch-to-batch consistency for European forensic toxicology, analytical chemistry, and pharmacological in vitro research laboratories. As a certified analytical reference standard, this pelletised form eliminates weighing variability, streamlines stock solution preparation, and supports high-throughput LC-MS/MS method validation workflows. Pure Lab Chems .eu stands as the definitive EU source for this rigorously characterised reagent, supplying each batch with a comprehensive certificate of analysis to underpin publishable, reproducible laboratory investigations across all member states.gov+2

Uncompromising Purity and Analytical Characterisation

Every lot of 2-METHYL-AP-237 HCl 20 mg pellets provided by Pure Lab Chems .eu is guaranteed to achieve a minimum purity of ≥99.0%, as determined by high-performance liquid chromatography (HPLC) with UV detection and corroborated by gas chromatography–mass spectrometry (GC-MS). This stringent purity specification ensures the material performs reliably as a certified reference standard (CRS) for quantitative toxicological screening, mass spectral library development, and receptor-binding assay calibration within controlled research environments.gov+1

Each shipment is accompanied by a batch-specific certificate of analysis (CoA) documenting the following critical quality attributes: chromatographic purity profile, residual solvent analysis (conforming to ICH Q3C guidelines), and heavy metal content limits (typically <10 ppm for lead, cadmium, arsenic, and mercury, aligned with European Pharmacopoeia specifications). The CoA further reports exact mass confirmation (322.1812 Da) via high-resolution mass spectrometry, providing laboratories with the data required for LC-MS/MS method development and forensic identification protocols.pubchem.ncbi.nlm.nih+1

Physically, the 20 mg pellets present as uniformly compressed, white to off-white discs or tablets, each containing a precisely metered quantity of 2-METHYL-AP-237 hydrochloride (molecular formula C₁₈H₂₇ClN₂O; molecular weight 322.9 g/mol). Pellet integrity and homogeneity are verified through weight variation testing (±2% tolerance), hardness assessment, and, where required, powder X-ray diffraction (PXRD) to confirm crystalline phase consistency across the compressed matrix. The hydrochloride salt form ensures enhanced aqueous solubility relative to the free base, facilitating rapid dissolution for stock solution preparation.pubchem.ncbi.nlm.nih+3

Such uncompromising purity and physical uniformity are indispensable for laboratories engaged in forensic toxicology, novel psychoactive substance (NPS) monitoring, or pharmacological in vitro profiling. Lower-grade industrial reagents, which may harbour uncharacterised impurities or exhibit pellet-to-pellet mass variability, introduce unacceptable uncertainty into analytical results, potentially undermining method validation, proficiency testing outcomes, and the reliability of mass spectral library entries. Pure Lab Chems .eu’s commitment to ≥99.0% purity and ±2% mass tolerance ensures that European researchers can generate data suitable for peer-reviewed publication and regulatory submission.gov+1

Principal Laboratory Applications and Research Methodologies

2-METHYL-AP-237 HCl 20 mg pellets serve several critical functions within controlled laboratory research settings, exclusively for in vitro investigation and analytical reference purposes:

Analytical Toxicology & Forensic Chemistry: As a certified reference material (CRM), the 20 mg pellet format of 2-METHYL-AP-237 hydrochloride is employed for mass spectral library development in LC-MS/MS and GC-MS platforms utilised by forensic laboratories across the EU. The pre-weighed pellet eliminates analytical balance variability, enabling precise preparation of calibration standards (e.g., 1 mg/mL stock solutions in methanol or acetonitrile) for method validation in toxicological screenings. The compound’s well-defined fragmentation pattern (parent mass 286.4 Da for the free base; 322.9 Da for the hydrochloride salt) facilitates differentiation from structural isomers such as AP-238 and para-methyl-AP-237, which share the same molecular formula but exhibit distinct mass spectral signatures.gov+2

Pharmacological In Vitro Assays: Within institutional frameworks (e.g., university research departments, contract research organisations, pharmaceutical R&D), the 20 mg pellet of 2-METHYL-AP-237 HCl is utilised as a selective μ-opioid receptor (MOR) agonist in receptor-binding affinity studies and cellular uptake assays. Its documented potency—approximately 4–5 times that of morphine in rodent behavioural models—makes it a valuable tool for probing opioid receptor pharmacology, G-protein versus β-arrestin signalling bias, and metabolic stability profiling using human hepatocyte cultures. The pellet format ensures consistent molar quantities across replicate experiments, reducing inter-assay variability. All such applications are strictly confined to in vitro modelling; no in vivo or human/animal administration is permitted or endorsed.gov

Chemical Synthesis & Reference Standardisation: The 20 mg pellet functions as a high-purity, pre-weighed analytical reference standard for monitoring synthetic reactions involving acyl piperazine scaffolds. Its well-characterised IUPAC name (1-[2-methyl-4-[(E)-3-phenylprop-2-enyl]piperazin-1-yl]butan-1-one;hydrochloride) and CAS Registry Number (98608-59-4) enable unambiguous identification in reaction monitoring, impurity profiling, and quality control workflows for novel opioid analogue research. The pelletised form streamlines addition to reaction vessels, minimising exposure to atmospheric moisture and reducing handling time.pubchem.ncbi.nlm.nih+2

Proficiency Testing & Inter-Laboratory Calibration: European forensic and toxicology laboratories incorporate 2-METHYL-AP-237 HCl 20 mg pellets into proficiency testing schemes to validate analytical competence in detecting emerging synthetic opioids. The pre-weighed format ensures consistent dosing across participating laboratories, supporting harmonisation of detection capabilities across EU member states and alignment with EMCDDA early warning system objectives and UNODC monitoring initiatives for new synthetic opioids (NSOs).gov+1

All applications described herein are intended solely for laboratory research purposes and must be conducted by qualified personnel within appropriate institutional frameworks, adhering to national and EU regulatory requirements for controlled substances.gov

Compound Stability, Optimal Storage, and Safe Handling Protocols

2-METHYL-AP-237 hydrochloride in pellet form exhibits moderate susceptibility to degradation under suboptimal storage conditions. The compressed matrix offers some protection against atmospheric moisture; however, the compound remains hygroscopic and may absorb water vapour, potentially leading to hydrolytic degradation of the amide bond. It is also sensitive to prolonged exposure to light and elevated temperatures, which can promote oxidative decomposition of the cinnamyl moiety.gov+1

Storage Protocols:

• Short-term storage: Desiccated conditions at +4°C (refrigerated), protected from light, for periods not exceeding 3 months. Pellets should be stored in airtight, light-resistant containers with desiccant packs.

• Long-term storage: Pellets should be stored at −20°C or −80°C in airtight, light-resistant containers with desiccant packs to maintain anhydrous conditions. Under these conditions, the compound remains stable for ≥24 months, as verified by periodic HPLC re-analysis.chemicalbook

Safe Handling Prerequisites: All manipulations of 2-METHYL-AP-237 HCl 20 mg pellets must be performed within a certified chemical fume hood by personnel wearing appropriate personal protective equipment (PPE), including nitrile gloves, safety goggles, and a laboratory coat. The compound should be handled as a potentially hazardous substance, given its classification as a potent μ-opioid receptor agonist and its scheduling under international drug control conventions (UN Single Convention on Narcotic Drugs, Schedule I).gov+1

Solubility for In Vitro Use: For preparation of stock solutions intended for in vitro assays, each 20 mg pellet dissolves readily in dimethyl sulfoxide (DMSO), anhydrous ethanol, or methanol to yield a 10 mM stock solution (approximately 6.2 mL solvent per pellet). Aqueous solubility is enhanced relative to the free base due to the hydrochloride salt form; however, stock solutions should be prepared fresh or aliquoted and stored at −20°C to prevent hydrolytic degradation. Working dilutions should be prepared immediately prior to use in assay buffers.pubchem.ncbi.nlm.nih+2
