1-[(3,4-Dimethoxyphenyl)sulfonyl]-4-ethynyl-1,4-dihydro-4-methyl-2H-3,1-benzoxazin-2-one CAS 2808410-67-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 387.41 g/mol gives 1-[(3,4-Dimethoxyphenyl)sulfonyl]-4-ethynyl-1,4-dihydro-4-methyl-2H-3,1-benzoxazin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-[(3,4-Dimethoxyphenyl)sulfonyl]-4-ethynyl-1,4-dihydro-4-methyl-2H-3,1-benzoxazin-2-one (CAS 2808410-67-3) is a high-purity analytical reference standard with the molecular formula C19H17NO6S and a molecular weight of 387.41 g/mol.

The molecular framework of 1-[(3,4-Dimethoxyphenyl)sulfonyl]-4-ethynyl-1,4-dihydro-4-methyl-2H-3,1-benzoxazin-2-one (C19H17NO6S) is characterized by a flavonoid core, an amide group, a sulfone 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
