Description
CATO supplies 3-(Tert-butyl)-4-((4-methoxyphenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 338747-73-2), a certified reference material (molecular formula C19H23NO4S, MW 361.46 g/mol) for analytical method development and quality control.
3-(Tert-butyl)-4-((4-methoxyphenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (C19H23NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(Tert-butyl)-4-((4-methoxyphenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine 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.
