2,5-Difluoro-4-(hydroxymethyl)benzoic acid CAS 1895356-29-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Difluoro-4-(hydroxymethyl)benzoic acid.

2,5-Difluoro-4-(hydroxymethyl)benzoic acid (CAS 1895356-29-2) is a high-purity analytical reference standard with the molecular formula C8H6F2O3 and a molecular weight of 188.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,5-Difluoro-4-(hydroxymethyl)benzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.13 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.

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.
