Description
As a certified reference material (CRM), 2-Bromo-1-(2,5-dimethylphenyl)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.
CATO supplies 2-Bromo-1-(2,5-dimethylphenyl)ethan-1-one (CAS 75840-13-0), a certified reference material (molecular formula C10H11BrO, MW 227.10 g/mol) for analytical method development and quality control.
2-Bromo-1-(2,5-dimethylphenyl)ethan-1-one (C10H11BrO) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
