Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.21 g/mol gives 3-fluoro-6-methoxy-2-methylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-fluoro-6-methoxy-2-methylbenzoic acid (CAS 220901-72-4) is a high-purity analytical reference standard with the molecular formula C9H15FO3 and a molecular weight of 190.21 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3-fluoro-6-methoxy-2-methylbenzoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.21 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.
