Benzamide is an organic compound with the chemical formula of C7H7NO. It is the simplest amide derivative of benzoic acid. In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [5] It is slightly soluble in water, [2] and soluble in many organic solvents. [6] It is a natural alkaloid found in the herbs of Berberis pruinosa . [6]
