Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-7-fluoro-2-methyl-2,3-dihydro-1H-inden-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.
4-Bromo-7-fluoro-2-methyl-2,3-dihydro-1H-inden-1-one (CAS 170927-05-6), molecular formula C10H8BrFO and molecular weight 243.07 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-7-fluoro-2-methyl-2,3-dihydro-1H-inden-1-one (C10H8BrFO) contains a hydroxyl group, an ether linkage, 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. 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.
