Acrylonitrile is a colorless liquid with a pungent odor and is flammable. Its vapor and air can form an explosive mixture. It is easy to cause burning when exposed to open flames and high heat, and emit toxic gases. Reacts violently with oxidants, strong acids, strong bases, amines and bromine.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily compiled and referenced. Acrylonitrile is in the list of 2B carcinogens.

Acrylonitrile is an important monomer for synthetic fibers, synthetic rubber and synthetic resins. Polyacrylonitrile fiber made from acrylonitrile, namely acrylic fiber, has properties very similar to wool, so it is also called synthetic wool. The copolymerization of acrylonitrile and butadiene can produce nitrile rubber, which has good oil resistance, cold resistance, abrasion resistance, and electrical insulation properties, and its performance is relatively stable under most chemical solvents, sunlight and heat. Acrylonitrile, butadiene, and styrene are copolymerized to prepare ABS resin, which has the advantages of light weight, cold resistance, and good impact resistance. Acrylonitrile hydrolysis can produce acrylamide and acrylic acid and its esters. They are important organic chemical raw materials. Acrylonitrile can also be electrolytically hydrogenated and coupled to produce adiponitrile, and hexamethylene diamine can be produced by hydrogenation of adiponitrile, which is a raw material for nylon 66. It can be used in the manufacture of water repellents and adhesives, etc., and is also used in other organic synthesis and pharmaceutical industries, and used as a cereal fumigant. In addition, this product is also an aprotic polar solvent, used as a raw material for PAC142, an oilfield mud additive.
Acrylonitrile is an important monomer for synthetic fibers, synthetic rubber and synthetic resins, as well as an intermediate for the insecticide chloramnil
