Methanediamine is the simplest geminal diamine. Its chemical formula is CH₂(NH₂)₂, and its structure consists of two amino groups on a central carbon atom. Although methanediamine only exists transiently in solution, its hydrochloride salt has been used in chemical synthesis since 1914. The hydrochloride is useful for the synthesis of primary amides from amino acids.
