Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,5-Dimethylphenyl)-7,8-dimethylquinoline-4-carboxylic acid.
2-(2,5-Dimethylphenyl)-7,8-dimethylquinoline-4-carboxylic acid (CAS 724749-08-0), molecular formula C20H19NO2 and molecular weight 305.37 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2,5-Dimethylphenyl)-7,8-dimethylquinoline-4-carboxylic acid (C20H19NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(2,5-Dimethylphenyl)-7,8-dimethylquinoline-4-carboxylic 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.
