HCONH2, commonly known as formamide, is a simple organic compound with the chemical formula consisting of a carbonyl group (C=O) attached to an amine group (NH2). It is a colorless liquid that is hygroscopic, meaning it can absorb moisture from the air. Formamide is used in various applications, including as a solvent in chemical reactions and as a precursor for the synthesis of other organic compounds. Formamide has a relatively high boiling point and is miscible with water, making it useful in laboratory settings. It is also studied for its potential role in the origins of life, as it can form amino acids and other essential biomolecules under certain conditions. Its structure and properties make it an interesting subject in both chemistry and biochemistry.
