5-Benzylidene-3-phenylimidazo[2,1-b]thiazol-6(5H)-one CAS 89990-78-3

Description

5-Benzylidene-3-phenylimidazo[2,1-b]thiazol-6(5H)-one (CAS 89990-78-3), molecular formula C18H12N2OS and molecular weight 304.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-Benzylidene-3-phenylimidazo[2,1-b]thiazol-6(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.37 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.

CATO manufactures 5-Benzylidene-3-phenylimidazo[2,1-b]thiazol-6(5H)-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.
