Chemical Structure
Description
As a certified reference material (CRM), 1-(3-Bromo-5-isopropylphenyl)ethan-1-one 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.
1-(3-Bromo-5-isopropylphenyl)ethan-1-one (CAS 1782470-88-5), molecular formula C11H13BrO and molecular weight 241.12 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Bromo-5-isopropylphenyl)ethan-1-one (C11H13BrO) contains a hydroxyl group, an ether linkage, 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. 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.
