Chemical compound From Wikipedia, the free encyclopedia

1-Nitronaphthalene is an organic compound with the formula C10H7NO2. It is one of two isomers of nitronaphthalene. A pale yellow, sublimable solid, 1-nitronaphthalene is the main product of the direct nitration of naphthalene. It is an intermediate in the production of naphthylamine, a precursor to dyes.[3] The conversion to the amine is effected by hydrogenation.[4]
