[4-(3-Fluoro-4-methylphenyl)phenyl]acetic acid CAS 1365272-72-5

Description

[4-(3-Fluoro-4-methylphenyl)phenyl]acetic acid (CAS 1365272-72-5) is a high-purity analytical reference standard with the molecular formula C15H13FO2 and a molecular weight of 244.26 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, [4-(3-Fluoro-4-methylphenyl)phenyl]acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
