7-Bromo-3,4-dihydro-2H-1-benzoxepin-5-one CAS 55580-08-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-3,4-dihydro-2H-1-benzoxepin-5-one.

CATO supplies 7-Bromo-3,4-dihydro-2H-1-benzoxepin-5-one (CAS 55580-08-0), a certified reference material (molecular formula C10H9BrO2, MW 241.08 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 7-Bromo-3,4-dihydro-2H-1-benzoxepin-5-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 7-Bromo-3,4-dihydro-2H-1-benzoxepin-5-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
