Chemical Structure

3-Chloro-4'-methoxy-3'-methyl-[1,1'-biphenyl]-4-ol CAS 1261982-82-4 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 3-Chloro-4'-methoxy-3'-methyl-[1,1'-biphenyl]-4-ol.

3-Chloro-4'-methoxy-3'-methyl-[1,1'-biphenyl]-4-ol (CAS 1261982-82-4), molecular formula C14H13ClO2 and molecular weight 248.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3-Chloro-4'-methoxy-3'-methyl-[1,1'-biphenyl]-4-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-Chloro-4'-methoxy-3'-methyl-[1,1'-biphenyl]-4-ol 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.
