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-4-fluoro-2'-methoxy-[1,1'-biphenyl]-2-carboxylic acid (CAS 1178334-17-2), a certified reference material (molecular formula C14H10ClFO3, MW 280.68 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-4-fluoro-2'-methoxy-[1,1'-biphenyl]-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 5'-Chloro-4-fluoro-2'-methoxy-[1,1'-biphenyl]-2-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.
