As a certified reference material (CRM), 8-Bromo-2,3,4,5-tetrahydro-1,5-benzothiazepin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
8-Bromo-2,3,4,5-tetrahydro-1,5-benzothiazepin-4-one (CAS 110766-85-3) is a high-purity analytical reference standard with the molecular formula C9H8BrNOS and a molecular weight of 258.13 g/mol.
Structurally, 8-Bromo-2,3,4,5-tetrahydro-1,5-benzothiazepin-4-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).
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.
