The occurrence of (2S,3S)-1-Chloro-2-hydroxy-3-[(benzyloxycarbonyl)amino]-4-(phenylthio)butane is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2S,3S)-1-Chloro-2-hydroxy-3-[(benzyloxycarbonyl)amino]-4-(phenylthio)butane (CAS 220365-47-9), molecular formula C18H20ClNO3S and molecular weight 365.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S,3S)-1-Chloro-2-hydroxy-3-[(benzyloxycarbonyl)amino]-4-(phenylthio)butane (C18H20ClNO3S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (2S,3S)-1-Chloro-2-hydroxy-3-[(benzyloxycarbonyl)amino]-4-(phenylthio)butane 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.
