2-Chloro-4-nitrotoluene

Chloronitrotoluene and 2,6-chlorotoluidine are technically important in other respects also. The former compound is the starting material for the prepara-oitn of 4,4 -dichloroindigo, which yields, on further chlorination or bromination, the very greenish 4,5,4, 5 -tetrahalogenindigos (e.g., brilliant indigo 4G). 2,6-Chloro-toluidine, as fast scarlet TR base, is used in generating ice colors (naphthol AS). The isomeric 4-chloro-2-toluidine (fast red KB base), prepared by reduction of the by-product 4-chloro-2-nitrotoluene, is used for the same purpose. 

Azoic Diazo Component 32, produced by nitration of >-chlorotoluene followed by reduction of the resulting 4-chloro-2-nitrotoluene and Azoic Diazo Component 34, produced by nitration of o-benzenesulfonotoluidide followed by hydrolysis. Va.ria.mine Blue B the half sulfate [6254-98 4] of (90), ie, Azoic Diazo Component 35 used for dark blue or green shades is marketed as the free base or half sulfate. It is produced by condensation of anisidine with 2-chloro-5-nitrobenzenesulfonic acid, reduction, and desulfonation of the resulting 5-amino-2- anisidinobenzenesulfonic acid.
