Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-4-oxo-1,4-dihydroquinoline-2-carboxylic acid.
6-Methyl-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (CAS 130064-09-4), molecular formula C11H9NO3 and molecular weight 203.19 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methyl-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (C11H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
