Nitrobenzene solution is widely used in the production of aniline, a key intermediate in the manufacture of dyes, pharmaceuticals, and rubber chemicals. It serves as a solvent in various industrial processes, particularly in the refining of lubricating oils and the synthesis of other organic compounds. Additionally, it is employed in the production of pesticides and herbicides, where it acts as a precursor or intermediate. In the fragrance industry, nitrobenzene is utilized in the synthesis of certain aromatic compounds. Its role as a masking agent in some industrial applications also makes it valuable for reducing the odor of other chemicals. However, its use requires careful handling due to its toxic and hazardous nature.
