4-(1,1-Dioxo-1,2-thiazolidin-2-yl)-2-methylbenzoic acid CAS 1282896-74-5

Description

4-(1,1-Dioxo-1,2-thiazolidin-2-yl)-2-methylbenzoic acid (CAS 1282896-74-5) is a high-purity analytical reference standard with the molecular formula C11H13NO4S and a molecular weight of 255.29 g/mol.

The molecular framework of 4-(1,1-Dioxo-1,2-thiazolidin-2-yl)-2-methylbenzoic acid (C11H13NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).

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 4-(1,1-Dioxo-1,2-thiazolidin-2-yl)-2-methylbenzoic 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.
