Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.17 g/mol gives D-Thiazolidine-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies D-Thiazolidine-4-carboxylic acid (CAS 45521-09-3), a certified reference material (molecular formula C4H7NO2S, MW 133.17 g/mol) for analytical method development and quality control.
The molecular framework of D-Thiazolidine-4-carboxylic acid (C4H7NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures D-Thiazolidine-4-carboxylic 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.
