Chemical Structure

5-Chloro-8-fluoro-4-hydroxyquinoline-3-carboxylic acid CAS 1019015-75-8 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 5-Chloro-8-fluoro-4-hydroxyquinoline-3-carboxylic acid (CAS 1019015-75-8), a certified reference material (molecular formula C10H5ClFNO3, MW 241.60 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, fluorine/chlorine substitution, 5-Chloro-8-fluoro-4-hydroxyquinoline-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 5-Chloro-8-fluoro-4-hydroxyquinoline-3-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.
