Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-(5-(((R)-2-Amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoic acid.
CATO supplies (S)-2-(5-(((R)-2-Amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoic acid (CAS 170006-72-1), a certified reference material (molecular formula C21H27N3O3S2C2HF3O2, MW 547.61 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-(5-(((R)-2-Amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoic acid (C21H27N3O3S2C2HF3O2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (S)-2-(5-(((R)-2-Amino-3-mercaptopropyl)amino)-[1,1'-biphenyl]-2-ylcarboxamido)-4-(methylthio)butanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
