 Methyl isocyanide (CAS NO.593-75-9) is mainly used for making 5-membered heterocyclic rings. Methyl isocyanide is useful for the preparation of various heterocycles. It is also a ligand in organometallic chemistry.

Methyl isocyanide was first prepared Gautier by reaction of silver cyanide with methyl iodide.[1][2] The common method for preparing methyl isocyanides is the dehydration of N-methylformamide.
