8-Bromo-3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl chloride CAS 953740-14-2

Description

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.

8-Bromo-3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl chloride (CAS 953740-14-2), molecular formula C9H8BrClO4S and molecular weight 327.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-Bromo-3,4-dihydro-2h-1,5-benzodioxepine-7-sulfonyl chloride (C9H8BrClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
