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 methyl (2R,4S)-4-sulfanylpyrrolidine-2-carboxylate;hydrochloride.
methyl (2R,4S)-4-sulfanylpyrrolidine-2-carboxylate;hydrochloride (CAS 2306249-53-4), molecular formula C6H11NO2SHCl and molecular weight 197.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl (2R,4S)-4-sulfanylpyrrolidine-2-carboxylate;hydrochloride (C6H11NO2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid 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. 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 methyl (2R,4S)-4-sulfanylpyrrolidine-2-carboxylate;hydrochloride 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.
