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 (4R)-2-Thioxo-4-thiazolidinecarboxylic Acid.
(4R)-2-Thioxo-4-thiazolidinecarboxylic Acid (CAS 98169-56-3) is a high-purity analytical reference standard with the molecular formula C4H5NO2S2 and a molecular weight of 163.22 g/mol.
The molecular framework of (4R)-2-Thioxo-4-thiazolidinecarboxylic Acid (C4H5NO2S2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (4R)-2-Thioxo-4-thiazolidinecarboxylic 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.
