Description
CATO manufactures [1,1'-biphenyl]-2,3-diol 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.
CATO supplies [1,1'-biphenyl]-2,3-diol (CAS 1133-63-7), a certified reference material (molecular formula C12H10O2, MW 186.21 g/mol) for analytical method development and quality control.
[1,1'-biphenyl]-2,3-diol (C12H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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.
