Chemical Structure
Description
(S)-methyl 2-(5-(((R)-2-amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoate hydrochloride (CAS 180977-34-8) is a high-purity analytical reference standard with the molecular formula C22H29N3O3S2HCl and a molecular weight of 484.07 g/mol.
The molecular framework of (S)-methyl 2-(5-(((R)-2-amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoate hydrochloride (C22H29N3O3S2HCl) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
