Description
CATO manufactures 5-Chloro-3'-(trifluoromethoxy)-[1,1'-biphenyl]-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.
CATO supplies 5-Chloro-3'-(trifluoromethoxy)-[1,1'-biphenyl]-3-carboxylic acid (CAS 1261519-01-0), a certified reference material (molecular formula C14H8ClF3O3, MW 316.66 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, 5-Chloro-3'-(trifluoromethoxy)-[1,1'-biphenyl]-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.66 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
