25373-69-7 3-ethyl-2-[3-(3-ethyl-1,3-benzoselenazol-2(3h)-ylidene)-2-methylprop-1-en-1-yl]-1,3-benzoselenazol-3-ium AR-1F3063 CAS 25373-69-7 chemical structure

Description

25373-69-7 3-ethyl-2-[3-(3-ethyl-1,3-benzoselenazol-2(3h)-ylidene)-2-methylprop-1-en-1-yl]-1,3-benzoselenazol-3-ium AR-1F3063 (C5H3Br2NO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
