Chem. Combining form of CARBON, used (instead of CARBO-) before vowels, in names of carbon compounds, as

  Carballylic (or tricarballylic) acid [ALLYL], a 3-basic acid obtained by the action of potash on allylic tricyanide; its salts are Carballylates. Carbanil [ANIL], an amido-derivative of the benzene group, cyanate of phenyl, CO=N–C₆ H₅, a mobile liquid with a pungent odor; hence Carbanilamide, NH·CO·NH–C₆ H₅, Carbanilic acid, HO·CO·NH–C₆ H₅, Carbanilide, CO=2(NH·C₆ H₅). Carbazol [AZO- + -OL], an amidophenyl, 2 C₆ H₄ = NH, occurring in coal-tar oil, and as a by-product in the manufacture of aniline. Carbazotic acid [AZOTIC], an earlier name of Picric acid; its salts are Carbazotates.
