Chemical Structure
Description
CATO supplies 6-Chloro-2-(2-isopropoxyphenyl)quinoline-4-carboxylic acid (CAS 932886-81-2), a certified reference material (molecular formula C19H16ClNO3, MW 341.79 g/mol) for analytical method development and quality control.
6-Chloro-2-(2-isopropoxyphenyl)quinoline-4-carboxylic acid (C19H16ClNO3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Chloro-2-(2-isopropoxyphenyl)quinoline-4-carboxylic acid 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.
