Tetraphenol :: Tetraphenol (n.) Furfuran.

Indophenol :: Indophenol (n.) 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. Simple indophenol proper has not yet been isolated..

Pyrogallol :: Pyrogallol (n.) A phenol metameric with phloroglucin, obtained by the distillation of gallic acid as a poisonous white crystalline substance having acid properties, and hence called also pyrogallic acid. It is a strong reducer, and is used as a developer in photography and in the production of certain dyes..

Trinitrophenol :: Trinitrophenol (n.) Picric acid.

Creosol :: Creosol (n.) A colorless liquid resembling phenol or carbolic acid, homologous with pyrocatechin, and obtained from beechwood tar and gum guaiacum..

Rosolic :: Rosolic (a.) Pertaining to, or designating, a complex red dyestuff (called rosolic acid) which is analogous to rosaniline and aurin. It is produced by oxidizing a mixture of phenol and cresol, as a dark red amorphous mass, C20H16O3, which forms weak salts with bases, and stable ones with acids. Called also methyl aurin, and, formerly, corallin..

Phthalein :: Phthalein (n.) One of a series of artificial organic dyes made as condensation products of the phenols with phthalic acid, and well represented by phenol phthalein. Their alkaline solutions are fluorescent..

Furfuran :: Furfuran (n.) A colorless, oily substance, C4H4O, obtained by distilling certain organic substances, as pine wood, salts of pyromucic acid, etc.; -- called also tetraphenol..

Nitrophnol :: Nitrophnol (n.) Any one of a series of nitro derivatives of phenol. They are yellow oily or crystalline substances and have well-defined acid properties, as picric acid..

Aurin :: Aurin (n.) A red coloring matter derived from phenol; -- called also, in commerce, yellow corallin..

Phenol :: Phenol (n.) 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..

Phloroglucin :: Phloroglucin (n.) A sweet white crystalline substance, metameric with pyrogallol, and obtained by the decomposition of phloretin, and from certain gums, as catechu, kino, etc. It belongs to the class of phenols. [Called also phloroglucinol.].

Naphthol :: Naphthol (n.) Any one of a series of hydroxyl derivatives of naphthalene, analogous to phenol. In general they are crystalline substances with a phenol (carbolic) odor..

Glucoside :: Glucoside (n.) One of a large series of amorphous or crystalline substances, occurring very widely distributed in plants, rarely in animals, and regarded as influental agents in the formation and disposition of the sugars. They are frequently of a bitter taste, but, by the action of ferments, or of dilute acids and alkalies, always break down into some characteristic substance (acid, aldehyde, alcohol, phenole, or alkaloid) and glucose (or some other sugar); hence the name. They are of the natur

Oxyphenic :: Oxyphenic (a.) Pertaining to, or designating, the phenol formerly called oxyphenic acid, and now oxyphenol and pyrocatechin. See Pyrocatechin..

Tyrosin :: Tyrosin (n.) A white crystalline nitrogenous substance present in small amount in the pancreas and spleen, and formed in large quantity from the decomposition of proteid matter by various means, -- as by pancreatic digestion, by putrefaction as of cheese, by the action of boiling acids, etc. Chemically, it consists of oxyphenol and amidopropionic acid, and by decomposition yields oxybenzoic acid, or some other benzol derivative..

Salicylic :: Salicylic (a.) Pertaining to, derived from, or designating, an acid formerly obtained by fusing salicin with potassium hydroxide, and now made in large quantities from phenol (carbolic acid) by the action of carbon dioxide on heated sodium phenolate. It is a white crystalline substance. It is used as an antiseptic, and in its salts in the treatment of rheumatism. Called also hydroxybenzoic acid..

Phenetol :: Phenetol (n.) The ethyl ether of phenol, obtained as an aromatic liquid, C6H5.O.C2H5..

Rufol :: Rufol (n.) A phenol derivative of anthracene obtained as a white crystalline substance, which on oxidation produces a red dyestuff related to anthraquinone..

Phenolate :: Phenolate (n.) A compound of phenol analogous to a salt.
