Xylidine

Xylidine

Xylidine can refer to any of the six isomers of xylene amine, or any mixture of them. All isomers are toxic.

The chemical formula of xylidines is C8H11N, or (CH3)2C6H3NH2. They are stable and combustible and react with strong oxidizing agents. They may be light sensitive. The CAS number for the isomer mixture is [1300-73-8]. They are typically yellow liquids (except 3,4-xylidine which is solid) that darken when exposed to air and light. They are miscible with ethanol and diethyl ether and little soluble in water.

Xylidines are produced as byproducts of fractional distillation of coal tar.

Their risk and safety phrases are R20 R22 R36 R37 R38.

Xylidines are chiefly used in production of pigments and dyestuffs, and also various antioxidants, agrochemicals, pharmaceuticals, and many other organic chemicals.

Xylidines are also used as a component of the Tonka rocket fuel.
