Cyano radical is a chemical species that contains a carbon atom and a nitrogen atom linked by a triple bond. Synonyms for cyano radical include cyanide radical, cyanide anion, and nitrile radical. These terms are often used interchangeably in organic chemistry to refer to the cyano group (-CN) and its related derivatives. The cyano radical is commonly found in organic synthesis and is used in the production of various pharmaceuticals, polymers, and agrochemicals. It is also an important intermediate in the conversion of aldehydes and ketones to nitriles, which are versatile building blocks for chemical synthesis. Synthesizing and manipulating cyano radicals is a valuable tool for chemists in designing new materials and creating novel chemical reactions.
