Description

Compared with other compounds in its class, the molecular weight of 270.28 g/mol gives 2-(5-(Isoxazol-3-ylmethylene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(5-(Isoxazol-3-ylmethylene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid (CAS 1022-55-5), a certified reference material (molecular formula C9H6N2O4S2, MW 270.28 g/mol) for analytical method development and quality control.

The molecular framework of 2-(5-(Isoxazol-3-ylmethylene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid (C9H6N2O4S2) 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.
