Chemical Structure

1,2-Difluoro-4,5-dimethoxybenzene CAS 203059-80-7 chemical structure

Description

The occurrence of 1,2-Difluoro-4,5-dimethoxybenzene is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Difluoro-4,5-dimethoxybenzene (CAS 203059-80-7), molecular formula C8H8F2O2 and molecular weight 174.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2-Difluoro-4,5-dimethoxybenzene (C8H8F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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 174.14 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.

As a certified reference material (CRM), 1,2-Difluoro-4,5-dimethoxybenzene 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.
