Chemical Structure

4,5-Dichloro-2-(difluoromethoxy)cinnamic acid CAS 1807333-85-2 chemical structure

Description

4,5-Dichloro-2-(difluoromethoxy)cinnamic acid (CAS 1807333-85-2) is a high-purity analytical reference standard with the molecular formula C10H6Cl2F2O3 and a molecular weight of 283.06 g/mol.

4,5-Dichloro-2-(difluoromethoxy)cinnamic acid (C10H6Cl2F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
