Chemical Structure
Description
2-Bromo-1-(2,5-dichlorophenyl)ethanone (CAS 7399-67-9), molecular formula C9H7BrO3 and molecular weight 243.05 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-1-(2,5-dichlorophenyl)ethanone (C9H7BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-1-(2,5-dichlorophenyl)ethanone 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.
