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.

The Uses of 3-Butenenitrile

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

What are the applications of Application

3-Butenenitrile is an antimicrobial

What are the applications of 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.

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ChEBI: 3-Butenenitrile is an aliphatic nitrile that is hydrogen cyanide in which the hydrogen has been replaced by an allyl group.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.
