Chemical Structure

2-Thioxothiazolidine-4-carboxylic Acid CAS 20933-67-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 163.22 g/mol gives 2-Thioxothiazolidine-4-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Thioxothiazolidine-4-carboxylic Acid (CAS 20933-67-9) 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 2-Thioxothiazolidine-4-carboxylic 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. 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.
