Disperse Orange 25 Usage And Synthesis
Chemical Propertiessolid
UsesDisperse orange 25 is an industrially utilized dye which can be used in a variety of photonic applications which include optical switches and modulators.
Preparation4-Nitrobenzenamine diazo, and N-ethyl-N-cyanoethylaniline?coupling.
General DescriptionDisperse orange 25 is an azo dye that is a non-ionic, aromatic compound which can be used in p-type semiconductors. It can improve the photo-thermal properties of electrochemical devices. Its stable chemical structure and large dipole moment make it useful as a non-linear optical (NLO) material.
