Chemical Structure
Description
CATO supplies 2-(2-Amino-4,5-dihydrothiazol-4-yl)acetic acid (CAS 103541-11-3), a certified reference material (molecular formula C5H8N2O2S, MW 160.19 g/mol) for analytical method development and quality control.
2-(2-Amino-4,5-dihydrothiazol-4-yl)acetic acid (C5H8N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl 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 2-(2-Amino-4,5-dihydrothiazol-4-yl)acetic 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.
