2-(2,3-Dichlorophenyl)-2,2-difluoroacetic acid CAS 1248094-19-0

Description

The occurrence of 2-(2,3-Dichlorophenyl)-2,2-difluoroacetic acid 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.

2-(2,3-Dichlorophenyl)-2,2-difluoroacetic acid (CAS 1248094-19-0) is a high-purity analytical reference standard with the molecular formula C8H4Cl2F2O2 and a molecular weight of 241.02 g/mol.

2-(2,3-Dichlorophenyl)-2,2-difluoroacetic acid (C8H4Cl2F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 2-(2,3-Dichlorophenyl)-2,2-difluoroacetic acid 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.
