3-Butenenitrile Chemical Properties,Uses,Production

Chemical Properties

clear colourless to yellow liquid. It has the smell of green onion and is extremely poisonous. Soluble in alcohol and ether, very slightly soluble in water.

Uses

Allyl cyanide is used as an anti-microbial. It is also used as pharmaceutical intermediates.

Preparation

3-Butenenitrile is synthesized by the reaction of allyl bromide and cuprous cyanide.

Definition

ChEBI: 3-Butenenitrile is an aliphatic nitrile that is hydrogen cyanide in which the hydrogen has been replaced by an allyl group. It has a role as a neurotoxin, a plant metabolite and an antifeedant. It is an aliphatic nitrile and an olefinic compound.

Application

Allyl cyanide is a substance whose toxicity originates through cyanide liberation. Allyl cyanide is also a degradation product of allyl isothiocyanate, a natural compound found in plants that have been shown to exhibit strong antimicrobial activity.
