Chemical Structure

Methyl 2,6-dichloro-4-(difluoromethoxy)benzoate CAS 1804882-55-0 chemical structure

Description

The occurrence of Methyl 2,6-dichloro-4-(difluoromethoxy)benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2,6-dichloro-4-(difluoromethoxy)benzoate (CAS 1804882-55-0) is a high-purity analytical reference standard with the molecular formula C9H6Cl2F2O3 and a molecular weight of 271.04 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, Methyl 2,6-dichloro-4-(difluoromethoxy)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.04 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.

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.
