2-(2,4-Dichlorophenyl)-3-(pyrazin-2-yl)thiazolidin-4-one CAS 89442-09-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 326.20 g/mol gives 2-(2,4-Dichlorophenyl)-3-(pyrazin-2-yl)thiazolidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2,4-Dichlorophenyl)-3-(pyrazin-2-yl)thiazolidin-4-one (CAS 89442-09-1), molecular formula C13H9Cl2N3OS and molecular weight 326.20 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2,4-Dichlorophenyl)-3-(pyrazin-2-yl)thiazolidin-4-one (C13H9Cl2N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
