Chemical Structure
Description
CATO supplies 2-(5-Chloro-2,4-dihydroxybenzoyl)benzoic acid (CAS 2513-23-7), a certified reference material (molecular formula C14H9ClO5, MW 292.67 g/mol) for analytical method development and quality control.
2-(5-Chloro-2,4-dihydroxybenzoyl)benzoic acid (C14H9ClO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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.
As a certified reference material (CRM), 2-(5-Chloro-2,4-dihydroxybenzoyl)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
