Chemical Structure
Description
2,2-Difluoro-2-(3-formylphenoxy)acetic acid (CAS 1153778-64-3) is a high-purity analytical reference standard with the molecular formula C9H6F2O4 and a molecular weight of 216.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,2-Difluoro-2-(3-formylphenoxy)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
