Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-Chloro-8-methyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride (CAS 1160263-52-4), a certified reference material (molecular formula C18H13Cl2NO, MW 330.21 g/mol) for analytical method development and quality control.
7-Chloro-8-methyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride (C18H13Cl2NO) 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; 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).
As a certified reference material (CRM), 7-Chloro-8-methyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
