carbazolen.

Brit.

/ˈkɑːbəzəʊl/, U.S.

/ˈkɑrbəˌzoʊl/

Forms: 1800s– carbazol, 1800s– carbazole.

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: carbo- comb. form, azo- comb. form, -ole suffix².

Etymology: < carbo- comb. form + azo- comb. form + -ole suffix², after German Carbazol (C. Graebe & C. Glaser 1872, in Berichte d. Deutsch. Chem. Ges. 5 13).

Chemistry.

A rather unreactive, crystalline, heterocyclic compound occurring in coal tar and as a by-product in the manufacture of aniline, used as an intermediate in dye manufacture.Carbazole has a tricyclic structure, with two benzene rings fused to a central pyrrole ring. Formula: C₁₂H₉N.
