2,3-Difluorobenzoyl chloride CAS 18355-73-2 chemical structure

Description

2,3-Difluorobenzoyl chloride (CAS 18355-73-2) is a high-purity analytical reference standard with the molecular formula C7H9ClF2O and a molecular weight of 182.60 g/mol.

Based on its molecular formula C7H9ClF2O, 2,3-Difluorobenzoyl chloride contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 182.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,3-Difluorobenzoyl chloride 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.
