Acrylonitrile 99% 500ml, monomer with polymerization inhibitor
Acrylonitrile is an organic compound with the formula CH2CHCN. It is a colorless volatile liquid although commercial samples can be yellow due to impurities. It has a pungent odor of garlic or onions. In terms of its molecular structure, it consists of a vinyl group linked to a nitrile. It is an important monomer for the manufacture of useful plastics such as polyacrylonitrile. It is reactive and toxic at low doses. Also, it was first synthesized by the French chemist Charles Moureu (1863–1929) in 1893.

Description
It is used principally as a monomer to prepare polyacrylonitrile, a homopolymer, or several important copolymers, such as styrene-acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), and other synthetic rubbers such as acrylonitrile butadiene (NBR). Hydrodimerization of this reagent affords adiponitrile, used in the synthesis of certain nylons:
- 2 CH2=CHCN + 2 e− + 2 H+ → NCCH2CH2CH2CH2CN
Small amounts are also used as a fumigant. Acrylonitrile 99% 500ml and derivatives, such as 2-chloroacrylonitrile, are dienophiles in Diels–Alder reactions. It is also a precursor in the industrial manufacture of acrylamide and acrylic acid.
