Uses

In the material field, 4-Benzoylbiphenyl serves as a highly efficient free - radical type II photoinitiator. It plays a crucial role in the UV polymerization process of corresponding resins when combined with tertiary amine complexing agents. For instance, in the production of varnishes, it enables rapid curing under UV light, forming a hard and durable film on the surface. In plastic coatings, it helps to enhance the adhesion and weather resistance of the coatings. It is also commonly used in wood coatings, adhesives, lithographic/screen printing inks, flexographic inks and other UV - curing coatings and inks.
In the medical field, 4-Benzoylbiphenyl acts as an intermediate for the synthesis of the antifungal drug bifonazole. Through specific chemical reactions, it contributes to the formation of bifonazole and other related drugs, which are widely used in the treatment of fungal infections.
