PhCONHPh

PhCONHPh refers to benzanilide, an organic compound with the chemical formula C13H11NO. It is a derivative of benzoic acid and aniline, where the carboxyl group of benzoic acid is replaced by an anilino group. Structurally, it consists of a phenyl ring attached to a carbonyl group, which is in turn attached to another phenyl ring via a nitrogen atom. This arrangement forms an amide linkage.

Benzanilide is a crystalline solid, typically white or off-white in appearance. It is relatively insoluble in water but soluble in many organic solvents such as ethanol and ether. The compound can be synthesized through various methods, most commonly by reacting benzoyl chloride with aniline, or by reacting benzoic acid with aniline under dehydrating conditions.

Historically, benzanilide has found applications as a plasticizer and as an intermediate in the synthesis of dyes and pharmaceuticals. It has also been investigated for its potential biological activities, although its widespread use in these areas may be limited. In organic chemistry research, benzanilide serves as a model compound for studying amide bond formation and reactivity. Its properties and synthesis are standard topics in organic chemistry curricula.
