3-(4-Bromophenyl)-3,5-dimethylpropiophenone CAS 898761-58-5

Description

The occurrence of 3-(4-Bromophenyl)-3,5-dimethylpropiophenone is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromophenyl)-3,5-dimethylpropiophenone (CAS 898761-58-5), molecular formula C17H17BrO and molecular weight 317.22 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Bromophenyl)-3,5-dimethylpropiophenone (C17H17BrO) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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.

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), 3-(4-Bromophenyl)-3,5-dimethylpropiophenone 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.
