Description

CATO manufactures 4-[(E)-2-({4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene)hydrazin-1-yl]benzoic 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.

4-[(E)-2-({4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene)hydrazin-1-yl]benzoic acid (CAS 339018-49-4), molecular formula C19H16ClN3O4S and molecular weight 417.87 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[(E)-2-({4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene)hydrazin-1-yl]benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
