A substance formally derived from ammonia by the replacement of one or more of the hydrogen atoms by hydrocarbon or other radicals. The substitution of one hydrogen atom constitutes a primary amine; that of two atoms, a secondary amine; that of three atoms, a tertiary amine; and that of four atoms, a quaternary ammonium ion, a positively charged ion isolated only in association with a negative ion. The amines form salts with acids.

(ă-mēn')

A substance derived from ammonia by the replacement of one or more of the hydrogen atoms by hydrocarbon or other radicals. The substitution of one hydrogen atom constitutes a primary amine, e.g., NH₂CH₃; that of two atoms, a secondary amine, e.g., NH(CH₃)₂; that of three atoms, a tertiary amine, e.g., N(CH₃)₃; and that of four atoms, a quaternary ammonium ion, e.g., ⁺N(CH₃)₄, a positively charged ion isolated only in association with a negative ion. The amines form salts with acids.
