Chemical Structure
Description
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.
1-Bromo-3-fluoro-2-(3-fluorophenyl)benzene (CAS 1233367-30-0), molecular formula C12H7BrF2 and molecular weight 269.08 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-3-fluoro-2-(3-fluorophenyl)benzene (C12H7BrF2) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 1-Bromo-3-fluoro-2-(3-fluorophenyl)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.
