Chemical Structure

1,3-Dichloro-4-(difluoromethoxy)benzene CAS 772-23-6 chemical structure

Description

The occurrence of 1,3-Dichloro-4-(difluoromethoxy)benzene is closely related to 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.

1,3-Dichloro-4-(difluoromethoxy)benzene (CAS 772-23-6) is a high-purity analytical reference standard with the molecular formula C7H4Cl2F2O and a molecular weight of 213.01 g/mol.

Structurally, 1,3-Dichloro-4-(difluoromethoxy)benzene (C7H4Cl2F2O) contains 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 213.01 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.

As a certified reference material (CRM), 1,3-Dichloro-4-(difluoromethoxy)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
