Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 295.60 g/mol gives 1-[2-BROMO-1-(4-CHLOROPHENYL) ETHYL]BENZENE distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[2-BROMO-1-(4-CHLOROPHENYL) ETHYL]BENZENE (CAS 885279-74-3), molecular formula C14H12BrCl and molecular weight 295.60 g/mol, is a CATO reference standard with documented purity and traceability.
1-[2-BROMO-1-(4-CHLOROPHENYL) ETHYL]BENZENE (C14H12BrCl) contains chlorine/bromine substitution, a polycyclic aromatic 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-[2-BROMO-1-(4-CHLOROPHENYL) ETHYL]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.
