| systematic name | As applied to chemical substances, a systematic name is composed of specially coined or selected words or syllables, each of which has a precisely defined chemical structural meaning, so that the structure may be derived from the name. Water (trivial name) is hydrogen oxide (systematic). The systematic name of histamine (a semisystematic name) is imidazolethylamine, which indicates that a radical of imidazole replaces one hydrogen atom of ethylamine, which in turn is an ethyl group attached to an amine group. Dimethyl sulfoxide states that two methyl radicals are attached to a sulfur atom that holds an oxygen atom. Carbolic acid (trivial name) or phenol (semisystematic name) are, systematically, phenyl hydroxide or hydroxybenzene. See: semisystematic name. (05 Mar 2000) |
