Chemical Structure

3,4-Dichloro-2-(difluoromethoxy)anisole CAS 1806321-35-6 chemical structure

Description

The occurrence of 3,4-Dichloro-2-(difluoromethoxy)anisole 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.

3,4-Dichloro-2-(difluoromethoxy)anisole (CAS 1806321-35-6), molecular formula C8H6Cl2F2O2 and molecular weight 243.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Dichloro-2-(difluoromethoxy)anisole (C8H6Cl2F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 243.03 g/mol, it falls into the medium-molecular-weight range. 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.
