Uncompromising Purity and Analytical Characterisation
Every lot of Phenibut HCl 25g powder provided by Pure Lab Chems .eu is guaranteed to achieve a minimum purity of ≥99%, as determined by high-performance liquid chromatography (HPLC) with UV detection and corroborated by nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography–mass spectrometry (LC-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 GABA receptor-binding assay calibration within controlled research environments.bodyhackguide
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 (215.68 Da for phenibut HCl; 179.22 Da for phenibut freebase) and monoisotopic mass verification via high-resolution mass spectrometry, providing laboratories with the data required for LC-MS/MS method development and forensic identification protocols.bodyhackguide
Physically, Phenibut HCl presents as a white to off-white crystalline powder or fine lyophilised solid, consistent with its hydrochloride salt form (molecular formula C₁₀H₁₄ClNO₂; molecular weight 215.68 g/mol). This appearance is verified through visual inspection under controlled lighting conditions and, where required, by powder X-ray diffraction (PXRD) to confirm crystalline phase homogeneity. The hydrochloride salt exhibits enhanced aqueous solubility (>100 mg/mL in water) and superior chemical stability relative to the freebase, facilitating preparation of stock solutions for in vitro assay calibration and extending shelf life under appropriate storage conditions.bodyhackguide
Such uncompromising purity and physical uniformity are indispensable for laboratories engaged in neuropharmacological research, GABA analogue screening, or analytical reference standardisation. Lower-grade industrial reagents, which may harbour uncharacterised impurities (e.g., synthetic byproducts, β-phenyl-γ-butyrolactam, or residual starting materials) or exhibit batch-to-batch 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% purity ensures that European researchers can generate data suitable for peer-reviewed publication and regulatory submission.
Principal Laboratory Applications and Research Methodologies
Phenibut HCl 25g powder serves several critical functions within controlled laboratory research settings, exclusively for in vitro investigation and analytical reference purposes:
Analytical Chemistry & Quality Control: As a certified reference material (CRM), Phenibut HCl is employed for mass spectral library development in LC-MS/MS and HPLC-UV platforms utilised by analytical laboratories across the EU. It supports method validation for quality control of nootropic formulations and forensic toxicological screenings, enabling accurate identification and quantification of this GABA analogue in seized materials, biological matrices, and synthetic reaction mixtures. The compound’s well-defined fragmentation pattern (parent mass 215.68 Da for HCl salt; 179.22 Da for freebase; characteristic fragments at m/z 161, 133, 105, and 77 corresponding to loss of water, CO₂, and phenyl moieties) facilitates differentiation from structural analogues such as GABA (γ-aminobutyric acid), baclofen (β-chlorophenyl-GABA), gabapentin, and pregabalin, which share related amino acid scaffolds but exhibit distinct mass spectral signatures.bodyhackguide
Neuropharmacological In Vitro Assays: Within institutional frameworks (e.g., university research departments, contract research organisations, pharmaceutical R&D), Phenibut HCl is utilised as a selective GABA_B receptor agonist in receptor-binding assays, electrophysiological studies, and neuronal cell culture models. Phenibut exhibits high affinity for GABA_B receptors (K_i in the low micromolar range), with negligible activity at GABA_A receptors at physiologically relevant concentrations. The compound also demonstrates weak agonist activity at α₂δ subunits of voltage-gated calcium channels, contributing to its anxiolytic and anticonvulsant-like effects in in vitro models. Phenibut serves as a valuable tool for probing GABAergic signalling, synaptic inhibition mechanisms, and neuronal network activity in hippocampal and cortical neuron cultures. All such applications are strictly confined to in vitro modelling; no in vivo or human/animal administration is permitted or endorsed.
Chemical Synthesis & Reference Standardisation: The 25g powder format functions as a high-purity, bulk analytical reference standard for monitoring synthetic reactions involving β-aryl-GABA scaffolds. Its well-characterised IUPAC name (4-amino-3-phenylbutanoic acid hydrochloride) and CAS Registry Number (1078-21-3 for HCl salt; 5492-33-1 for freebase) enable unambiguous identification in reaction monitoring, impurity profiling, and quality control workflows for GABA analogue research. The powder form streamlines addition to reaction vessels or assay buffers, minimising exposure to atmospheric moisture and reducing handling time for bulk-scale experiments.bodyhackguide
Structure–Activity Relationship (SAR) Studies: European medicinal chemistry laboratories incorporate Phenibut HCl into SAR investigations to elucidate the impact of β-phenyl substitution on the GABA scaffold on GABA_B receptor affinity, metabolic stability, and blood-brain barrier permeability. Comparative studies against GABA, baclofen, gabapentin, pregabalin, and other GABA analogues support rational design of novel GABAergic ligands with tailored pharmacokinetic profiles. The β-phenyl moiety enhances lipophilicity and CNS penetration relative to unsubstituted GABA, while the hydrochloride salt confers enhanced aqueous solubility and chemical stability for analytical applications.
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 and analytical reference materials.
Compound Stability, Optimal Storage, and Safe Handling Protocols
Phenibut HCl exhibits excellent stability under appropriate storage conditions. The hydrochloride salt form confers enhanced chemical stability and oxidative resistance relative to the freebase; however, the compound remains sensitive to prolonged exposure to light, moisture, and elevated temperatures, which can promote degradation or hydrolysis.bodyhackguide
Storage Protocols:
-
Short-term storage: Desiccated conditions at +15°C to +25°C (controlled room temperature), protected from light, for periods not exceeding 24 months. Powder should be stored in airtight, light-resistant containers with desiccant packs.
-
Long-term storage: Powder should be stored at +4°C (refrigerated) or −20°C (frozen) in airtight, light-resistant containers with desiccant packs to maintain anhydrous conditions. Under these conditions, the compound remains stable for ≥36 months, as verified by periodic HPLC re-analysis.
Safe Handling Prerequisites: All manipulations of Phenibut HCl powder 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 pharmacological activity as a GABA_B receptor agonist. Powder should not be inhaled or allowed to contact skin or eyes.
Solubility for In Vitro Use: For preparation of stock solutions intended for in vitro assays, Phenibut HCl is freely soluble in water (>100 mg/mL), dimethyl sulfoxide (DMSO), anhydrous ethanol, and methanol. Stock solutions should be prepared in deionised water, DMSO, or methanol at concentrations up to 10–100 mM, then diluted into assay buffers containing ≤1% organic solvent if necessary. Stock solutions in water should be prepared fresh or aliquoted and stored at −20°C to prevent microbial contamination. Working dilutions should be prepared immediately prior to use in assay buffers.bodyhackguide
