Chemical Structure
Description
The occurrence of 7-Bromo-3,4-dihydrobenzo[f][1,4]thiazepin-5(2H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Bromo-3,4-dihydrobenzo[f][1,4]thiazepin-5(2H)-one (CAS 14944-02-6), molecular formula C9H8BrNOS and molecular weight 258.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Bromo-3,4-dihydrobenzo[f][1,4]thiazepin-5(2H)-one (C9H8BrNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 258.13 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.
