APPLICATIONS
The prefix nitro- indicates the presence of NO2- radical, while nitrate refers to any salt or ester of nitric acid or the NO3- anion. Nitroso- is the prefix indicating presence of the group -NO and azo- is for -N=N- group. Some range of  organic compounds containing nitrogen include nitro compounds (RNO2 ), nitroso compounds (RNO), amines (R3N ), amino acids, and natural alkaloids or nucleotides. The nitrogen ion in nitro compounds is trigonally planar with 120° angles. There are two resonance bonds so that the two oxygens are equivalent. Nitro compounds are strongly basic due to electron withdrawing both inductively and mesomerically. Historically, they are abundant in dyes and explosives. Nitro compounds, organic hydrocarbons having one or more NO2 groups bonded via nitrogen to the carbon framework, are versatile intermediate in organic synthesis.

1-Nitronaphthalene is used as for the preparation dye intermediates such as 1-naphthylamine (by catalytic reduction), 1-nitronaphthalene-5-sulfonic acid (by sulfonation) and dinitronaphthalenes (by additional nitration). 1-Nitronaphthalene is also used as a component in the formulation of nitrate explosives to decrease the burning rate and as a deblooming agent for petroleum and oils. It is also used as an intermediate to produce raticides.
