Benzamide is an off-white solid with the chemical formula of C6H5CONH2. It is a derivative of benzoic acid. It is slightly soluble in water, and soluble in many organic solvents.

Chemical derivatives[edit]

A number of substituted benzamides exist, including:

The sedatives trimetozine, Diclometide and tricetamide, the CNS stimulants ethamivan, and nikethamide, the anthelmintic agents niclosamide, clioxanide and bromoxanide, the coccidiostat aklomide, and the antiarrhythmic agent capobenic acid are all made from the corresponding benzoic acids in obvious ways.
