Chemical Structure

4-Hydroxy-4'-(trifluoromethyl)-[1,1'-biphenyl]-3-carboxylic acid CAS 43029-72-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxy-4'-(trifluoromethyl)-[1,1'-biphenyl]-3-carboxylic acid.

4-Hydroxy-4'-(trifluoromethyl)-[1,1'-biphenyl]-3-carboxylic acid (CAS 43029-72-7), molecular formula C14H9F3O3 and molecular weight 282.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Hydroxy-4'-(trifluoromethyl)-[1,1'-biphenyl]-3-carboxylic acid (C14H9F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 282.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Hydroxy-4'-(trifluoromethyl)-[1,1'-biphenyl]-3-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.
