Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Chloro-2-(m-tolyl)quinoline-4-carboxylic acid.
8-Chloro-2-(m-tolyl)quinoline-4-carboxylic acid (CAS 588677-32-1), molecular formula C17H12ClNO2 and molecular weight 297.74 g/mol, is a CATO reference standard with documented purity and traceability.
8-Chloro-2-(m-tolyl)quinoline-4-carboxylic acid (C17H12ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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 8-Chloro-2-(m-tolyl)quinoline-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.
