Chemical Structure
Description
Structurally, (2S,3S)-N2-(4-(Benzo[d]thiazol-2-ylcarbamoyl)phenyl)-N3-(3,4-dichlorophenyl)-N2-(4-fluorobenzyl)oxirane-2,3-dicarboxamide (C31H21Cl2FN4O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 635.49 g/mol, it falls into the 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).
(2S,3S)-N2-(4-(Benzo[d]thiazol-2-ylcarbamoyl)phenyl)-N3-(3,4-dichlorophenyl)-N2-(4-fluorobenzyl)oxirane-2,3-dicarboxamide (CAS 1639140-80-9), molecular formula C31H21Cl2FN4O4S and molecular weight 635.49 g/mol, is a CATO reference standard with documented purity and traceability.
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.
