Premium 2-Methyl-AP-237 HCl Powder – Laboratory Grade Research Chemical

biosynlab supplies pharmaceutical-grade 2-Methyl-AP-237 HCl Powder for sophisticated scientific research and analytical applications. As a trusted vendor of synthetic opioid analogs to laboratories across the USA, United Kingdom, and European Union, we deliver consistently pure, accurately measured compounds essential for reproducible experimental protocols and advanced pharmacological studies.

Chemical Composition & Structure

2-Methyl-AP-237 (systematic name: 2-methyl-1-butyryl-4-(p-aminobenzoyl)piperazine hydrochloride) is a synthetic piperazine derivative structurally related to AP-237 (Bucinnazine). The addition of a 2-methyl substituent on the piperazine ring distinguishes this analog from the parent compound. The molecular formula C₁₆H₂₃N₃O₂ · HCl yields a molecular weight of 325.84 g/mol for the hydrochloride salt.

As a structural analog of the pharmaceutical opioid AP-237, 2-Methyl-AP-237 has emerged as a compound of interest in research examining structure-activity relationships within the piperazine class of opioid receptor ligands. The hydrochloride salt form provides enhanced stability, improved water solubility, and superior handling characteristics compared to the freebase form.

Research Applications

biosynlab 2-Methyl-AP-237 HCl Powder serves as standardized reference material for:

• Opioid receptor pharmacology (μ-opioid, κ-opioid, δ-opioid)
• Structure-activity relationship (SAR) studies on piperazine opioids
• Comparative binding affinity assays with AP-237 and related analogs
• Metabolism and pharmacokinetic research
• Analytical method development (HPLC, GC-MS, LC-MS/MS)
• Forensic toxicology reference standards
• Receptor subtype selectivity investigations
• Cross-reactivity testing in immunoassays

Researchers utilize 2-Methyl-AP-237 alongside related synthetic opioids including AP-237, AP-238, and comparative studies with traditional opiates to advance understanding of piperazine-based opioid pharmacology and structure-activity relationships.
