| | Indophenol | n. [ Indigo + phenol. ] (Chem.) Any one of a series of artificial blue dyestuffs, resembling indigo in appearance, and obtained by the action of phenol on certain nitrogenous derivatives of quinone.

A phenol, C6H4(OH)2, produced by the distillation of catechin; called also oxyphenic acid, and now pyrocatechin. [ 1913 Webster ] | | Phenol | n. [ Gr. fai`nein to show + -ol: cf. F. phénol. ] (Chem.) 1. A white or pinkish crystalline substance, C6H5OH, produced by the destructive distillation of many organic bodies, as wood, coal, etc., and obtained from the heavy oil from coal tar. [ 1913 Webster ] ☞ It has a peculiar odor, somewhat resembling creosote, which is a complex mixture of phenol derivatives. It is of the type of alcohols, and is called also phenyl alcohol, but has acid properties, and hence is popularly called carbolic acid, and was formerly called phenic acid. It is a powerful caustic poison, and in dilute solution has been used as an antiseptic. [ 1913 Webster ] 2. Any one of the series of hydroxyl derivatives of which phenol proper is the type.
