Chemical Structure
Description
The occurrence of 2-Bromo-4-fluoro-3-methyl-1-(trifluoromethyl)benzene 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 2-Bromo-4-fluoro-3-methyl-1-(trifluoromethyl)benzene (CAS 2167902-49-8), a certified reference material (molecular formula C8H5BrF4, MW 257.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H5BrF4, 2-Bromo-4-fluoro-3-methyl-1-(trifluoromethyl)benzene contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.02 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.
CATO manufactures 2-Bromo-4-fluoro-3-methyl-1-(trifluoromethyl)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
