Chemical Structure
Description
CATO supplies (S)-2-Amino-3-hydroxypropane-1-sulfonic acid (CAS 16421-58-2), a certified reference material (molecular formula C3H9NO4S, MW 155.17 g/mol) for analytical method development and quality control.
(S)-2-Amino-3-hydroxypropane-1-sulfonic acid (C3H9NO4S) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. 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-hydroxypropane-1-sulfonic 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.
