Chemical Structure

4-((4-Oxo-2-thioxothiazolidin-3-yl)methyl)benzoic acid CAS 536727-51-2 chemical structure

Description

CATO supplies 4-((4-Oxo-2-thioxothiazolidin-3-yl)methyl)benzoic acid (CAS 536727-51-2), a certified reference material (molecular formula C11H9NO3S2, MW 267.32 g/mol) for analytical method development and quality control.

The molecular framework of 4-((4-Oxo-2-thioxothiazolidin-3-yl)methyl)benzoic acid (C11H9NO3S2) 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 its high hydrophobicity (logP), 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
