Description
CATO supplies 2-Hydroxy-5-(phenylethynyl)benzoic acid (CAS 32192-74-8), a certified reference material (molecular formula C15H10O3, MW 238.24 g/mol) for analytical method development and quality control.
2-Hydroxy-5-(phenylethynyl)benzoic acid (C15H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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-Hydroxy-5-(phenylethynyl)benzoic 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.
