3-(2,4-Dichlorophenyl)-2-(pyrazin-2-yl)thiazolidin-4-one CAS 89442-15-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,4-Dichlorophenyl)-2-(pyrazin-2-yl)thiazolidin-4-one.

3-(2,4-Dichlorophenyl)-2-(pyrazin-2-yl)thiazolidin-4-one (CAS 89442-15-9), molecular formula C13H9Cl2N3OS and molecular weight 326.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2,4-Dichlorophenyl)-2-(pyrazin-2-yl)thiazolidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 3-(2,4-Dichlorophenyl)-2-(pyrazin-2-yl)thiazolidin-4-one 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.
