4-Cyanobenzoic acid

Description:

4-Cyanobenzoic acid, also known as p-cyanobenzoic acid, is an aromatic carboxylic acid characterized by the presence of both a cyano group (-CN) and a carboxylic acid group (-COOH) attached to a benzene ring. Its molecular formula is C8H6N02, and it features a cyanide functional group positioned para to the carboxylic acid on the benzene ring. This compound typically appears as a white to light yellow crystalline solid and is soluble in polar organic solvents. It exhibits moderate acidity due to the carboxylic acid group, which can donate a proton in solution. The presence of the electron-withdrawing cyano group enhances the acidity of the carboxylic acid compared to benzoic acid. 4-Cyanobenzoic acid is utilized in various applications, including as a building block in organic synthesis, in the production of pharmaceuticals, and as a reagent in chemical research. Its unique properties make it valuable in the development of materials and in the study of chemical reactions involving aromatic compounds.

4-Cyanobenzoic acid

CAS: 619-65-8

4-Cyanobenzoic acid (4CB) is a benzene derivative that inhibits the activity of tyrosinase, an enzyme involved in the production of melanin. It is synthesized by reacting 2,4-dichlorobenzoic acid with sodium hydroxide and acetone. 4CB has been shown to have a potent inhibitory effect on the enzyme, with an isolated yield of up to 83%. The compound also shows strong hydrogen bonding interactions with water molecules and coordinates in a geometry where one of its oxygen atoms is double bonded to two nitrogen atoms. This structural analysis suggests that 4 CB may bind to tyrosinase through adsorption mechanism.
