2-Chloroaniline is the raw material of herbicide green sulfuron, and also an important dye intermediate. It is the color base of ice dyeing dyestuff and can also be used as the diazo component of azo dyestuff to produce acid black, acid blue and organic color precipitation water solid yellow R, permanent red FR, Hansa yellow HR, etc.
