2-Nitrodiphenylamine , NDPA for short or 2-NDPA is an orange-red organic compound , a nitrated derivative of the aromatic amine diphenylamine and is isomeric to 3-nitrodiphenylamine and 4-nitrodiphenylamine .
properties
2-Nitrodiphenylamine is strongly polar and has an electrical dipole moment of 4.13 Debye (at 20 ° C in a benzene solution). The orange-colored, crystalline compound still dissolves little in water, but does well in ethanol .
use
2-Nitrodiphenylamine is used as a stabilizer of fuels - such as Otto II fuel - and explosives as well as in the manufacture of synthetic rubber and other polymers. The compound is also used in some synthetic routes in organic chemistry. As a 5 mM solution in dilute sulfuric acid , NDPA is used as a redox indicator for the titrimetric determination of Fe 2+ ions.
