8-Bromo-3,4-dihydro-2H-benzo[b][1,4,5]oxathiazepine 1,1-dioxide CAS 1363593-70-7

Description

As a certified reference material (CRM), 8-Bromo-3,4-dihydro-2H-benzo[b][1,4,5]oxathiazepine 1,1-dioxide 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-3,4-dihydro-2H-benzo[b][1,4,5]oxathiazepine 1,1-dioxide (CAS 1363593-70-7), molecular formula C8H8BrNO3S and molecular weight 278.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 8-Bromo-3,4-dihydro-2H-benzo[b][1,4,5]oxathiazepine 1,1-dioxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
