2-(4-Fluoro-2-methylphenoxy)acetic acid CAS 451-88-7

Description

Compared with other compounds in its class, the molecular weight of 184.16 g/mol gives 2-(4-Fluoro-2-methylphenoxy)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Fluoro-2-methylphenoxy)acetic acid (CAS 451-88-7) is a high-purity analytical reference standard with the molecular formula C9H9FO3 and a molecular weight of 184.16 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(4-Fluoro-2-methylphenoxy)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.16 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.
