Chemical Structure
Description
The molecular framework of 2,3-Difluoro-6-methoxybenzoic acid methyl ester (C9H8F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2,3-Difluoro-6-methoxybenzoic acid methyl ester (CAS 773876-05-4) is a high-purity analytical reference standard with the molecular formula C9H8F2O3 and a molecular weight of 202.15 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
