3-(2,5-Dioxopyrrolidin-1-yl)-N-(3,5,7-trimethylbenzo[d]thiazol-2(3H)-ylidene)benzamide (CAS 868369-91-9), molecular formula C21H19N3O3S and molecular weight 393.46 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(2,5-Dioxopyrrolidin-1-yl)-N-(3,5,7-trimethylbenzo[d]thiazol-2(3H)-ylidene)benzamide (C21H19N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 393.46 g/mol, it falls into the moderately-high-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.
