Chemical Structure
Description
Ethyl 3-bromo-4-chloro-5-fluorobenzoate (CAS 1160574-71-9), molecular formula C9H7BrClFO2 and molecular weight 281.51 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 3-bromo-4-chloro-5-fluorobenzoate (C9H7BrClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. 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 Ethyl 3-bromo-4-chloro-5-fluorobenzoate 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.
