Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-(tert-Butyl)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (CAS 1267211-60-8), a certified reference material (molecular formula C14H19NO2, MW 233.31 g/mol) for analytical method development and quality control.
6-(tert-Butyl)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (C14H19NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 6-(tert-Butyl)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-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.
