Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-3-chloro-5-nitrobenzoic acid.
2-Bromo-3-chloro-5-nitrobenzoic acid (CAS 1499553-66-0) is a high-purity analytical reference standard with the molecular formula C7H3BrClNO4 and a molecular weight of 280.46 g/mol.
2-Bromo-3-chloro-5-nitrobenzoic acid (C7H3BrClNO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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-3-chloro-5-nitrobenzoic acid 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.
