Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Chlorophenyl)-2-(4-fluorophenyl)acetic acid.

2-(4-Chlorophenyl)-2-(4-fluorophenyl)acetic acid (CAS 51535-39-8), molecular formula C14H10ClFO2 and molecular weight 264.68 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(4-Chlorophenyl)-2-(4-fluorophenyl)acetic acid (C14H10ClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 264.68 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).

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.
