Description
Compared with other compounds in its class, the molecular weight of 284.15 g/mol gives 3-(4-Bromobutyl)-5-methylbenzo[d]oxazol-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(4-Bromobutyl)-5-methylbenzo[d]oxazol-2(3H)-one (CAS 1380498-74-7), a certified reference material (molecular formula C12H14BrNO2, MW 284.15 g/mol) for analytical method development and quality control.
3-(4-Bromobutyl)-5-methylbenzo[d]oxazol-2(3H)-one (C12H14BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 3-(4-Bromobutyl)-5-methylbenzo[d]oxazol-2(3H)-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.
