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-Amino-3-(methylsulfonyl)propanoic acid.
(S)-2-Amino-3-(methylsulfonyl)propanoic acid (CAS 1065052-07-4) is a high-purity analytical reference standard with the molecular formula C4H9NO4S and a molecular weight of 167.18 g/mol.
(S)-2-Amino-3-(methylsulfonyl)propanoic acid (C4H9NO4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (S)-2-Amino-3-(methylsulfonyl)propanoic 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.
