Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Bromoacetyl-3,4-dihydro-1,5-benzodioxepin (CAS 35970-34-4), molecular formula C11H11BrO3 and molecular weight 271.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 7-Bromoacetyl-3,4-dihydro-1,5-benzodioxepin is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.11 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.
CATO manufactures 7-Bromoacetyl-3,4-dihydro-1,5-benzodioxepin 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.
