2cyanopropanal

2cyanopropanal, also known as 2-cyano-3-oxopropanal, is an organic compound with the chemical formula CH3CH(CN)CHO. It is a derivative of propanal, where one hydrogen atom has been replaced by a cyano group (CN) and another hydrogen atom has been replaced by a formyl group (CHO). This compound is a colorless liquid at room temperature and has a pungent odor.

2cyanopropanal is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. Its cyano group can undergo various reactions, such as hydrolysis to form carboxylic acids or reduction to form amines. The formyl group can also be used for further functionalization, such as in the synthesis of heterocyclic compounds.

The compound is typically prepared through the reaction of propanal with cyanide ions in the presence of a catalyst. The reaction proceeds via an addition-elimination mechanism, where the cyanide ion adds to the carbonyl group of propanal, followed by elimination of a hydroxide ion to form the cyano group.

2cyanopropanal is a reactive compound and should be handled with care. It is classified as a hazardous substance and should be stored in a cool, dry place away from heat sources and incompatible substances. Proper personal protective equipment, such as gloves and safety glasses, should be worn when handling this compound.
