5-(2-Methylbenzyl)-2-(phenylamino)thiazol-4(5H)-one (CAS 219554-73-1), molecular formula C17H16N2OS and molecular weight 296.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(2-Methylbenzyl)-2-(phenylamino)thiazol-4(5H)-one (C17H16N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 296.39 g/mol, it falls into the medium-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
