A tertiary amine is a type of organic compound that contains a nitrogen atom bonded to three carbon-containing groups, known as alkyl or aryl groups. Unlike primary and secondary amines, which have one or two carbon groups respectively, tertiary amines do not have any hydrogen atoms directly attached to the nitrogen. This structure influences their chemical properties and reactivity. Tertiary amines are commonly used in various applications, including as solvents, catalysts, and in the production of pharmaceuticals. They can also act as bases and nucleophiles in chemical reactions. Examples of tertiary amines include triethylamine and N,N-dimethylbenzylamine.
