Chemical Structure
Description
2-bromo-1-chloro-3-(trifluoromethoxy)benzene (CAS 1805185-81-2) is a high-purity analytical reference standard with the molecular formula C7H9BrClF3O and a molecular weight of 281.50 g/mol.
2-bromo-1-chloro-3-(trifluoromethoxy)benzene (C7H9BrClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-bromo-1-chloro-3-(trifluoromethoxy)benzene 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.
