Description
As a certified reference material (CRM), 3-chloro-3'-(methylsulfonyl)-[1,1'-biphenyl]-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.
3-chloro-3'-(methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid (CAS 1261913-06-7) is a high-purity analytical reference standard with the molecular formula C14H11ClO4S and a molecular weight of 310.75 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3-chloro-3'-(methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.75 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
