Chemical Structure
Description
The occurrence of 5-Bromo-1-(difluoromethyl)-2,3-difluorobenzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Bromo-1-(difluoromethyl)-2,3-difluorobenzene (CAS 1805422-92-7), a certified reference material (molecular formula C7H3BrF4, MW 243.00 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H3BrF4, 5-Bromo-1-(difluoromethyl)-2,3-difluorobenzene contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 5-Bromo-1-(difluoromethyl)-2,3-difluorobenzene 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.
