8-Bromo-2,2,4-trimethyl-6-(methylsulfonyl)-2H-benzo[b][1,4]oxazin-3(4H)-one CAS 1820889-84-6

Description

The molecular framework of 8-Bromo-2,2,4-trimethyl-6-(methylsulfonyl)-2H-benzo[b][1,4]oxazin-3(4H)-one (C12H14BrNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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).
