Chemical Structure
Description
The occurrence of 4-(Tert-butyl) 6-methyl 2,3-dihydro-4H-benzo[b][1,4]oxazine-4,6-dicarboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(Tert-butyl) 6-methyl 2,3-dihydro-4H-benzo[b][1,4]oxazine-4,6-dicarboxylate (CAS 648449-53-0) is a high-purity analytical reference standard with the molecular formula C15H19NO5 and a molecular weight of 293.32 g/mol.
The molecular framework of 4-(Tert-butyl) 6-methyl 2,3-dihydro-4H-benzo[b][1,4]oxazine-4,6-dicarboxylate (C15H19NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
