Description and Uses
2-Nitrotoluene is a light yellow to darker yellow-green liquid. It is used for the synthesis of a variety of industrial products. These include to synthesise agricultural and rubber chemicals, azo and sulphur dyes, and dyes for cotton, wool, silk, leather, and paper. O-nitrotoluene decomposes on contact with strong oxidants, reducing agents, acids, or bases producing toxic fumes, nitrogen oxides, and carbon monoxide.
2-Nitrotoluene is used as an intermediate for the o-toludine synthesis, which finds application in the dyestuff industry. It is employed as a reagent in detecting and photometric determining oxidizing agent. It is also used in the determination of prussic acid content in the air. It acts as a precursor to prepare 2-amino-4-chlorotoluene, 2-amino-6-chlorotoluene, nitrotoluenesulfonic acids and toluene nitrosulfonic chlorides. It acts as a nitrogen supplement in the culture medium of pseudomonas sp. strain ClS1. It acts as a carbon and energy supplement in the culture medium of Pseudomonas sp. strain JS42.
