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 6-Chloro-2-hydroxyquinoline-4-carboxylic acid, 97% (CAS 32431-30-4), a certified reference material (molecular formula C10H6ClNO3, MW 223.61 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-2-hydroxyquinoline-4-carboxylic acid, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 6-Chloro-2-hydroxyquinoline-4-carboxylic acid, 97% 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.
