Chemical Structure

4-Chloro-2,6-difluorobenzoyl chloride CAS 272104-45-7 chemical structure

Description

The occurrence of 4-Chloro-2,6-difluorobenzoyl chloride 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.

4-Chloro-2,6-difluorobenzoyl chloride (CAS 272104-45-7) is a high-purity analytical reference standard with the molecular formula C7H2Cl2F2O and a molecular weight of 210.99 g/mol.

Structurally, 4-Chloro-2,6-difluorobenzoyl chloride (C7H2Cl2F2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 210.99 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
