Applications of Benzophenone

Benzophenone (CAS 119-61-9) is a highly versatile compound with wide applications across multiple industries. Its UV-absorbing properties, stability, and reactivity make it a valuable raw material in coatings, adhesives, cosmetics, pharmaceuticals, and fragrances.

Paints, Inks & Coatings

As a photoinitiator, Benzophenone plays a vital role in UV-curing technology. It initiates polymerization under ultraviolet light, enabling fast curing of paints, inks, and varnishes. This results in improved durability, scratch resistance, and production efficiency.

Adhesives & Polymers

Benzophenone is widely used in UV-cured adhesives, offering quick setting times and high bonding strength, especially in electronics, medical devices, and construction applications. In the polymer industry, it acts as a UV stabilizer, protecting plastics from degradation and extending product lifespan under sunlight exposure.

Cosmetics & Personal Care

With its ability to absorb UV rays, Benzophenone is a key ingredient in sunscreens, nail polishes, and personal care formulations. It helps protect products from light-induced damage, ensuring safety and stability for end users.

Pharmaceutical Intermediate

In the pharmaceutical sector, Benzophenone serves as an intermediate in the synthesis of active pharmaceutical ingredients (APIs). Its stable structure makes it an ideal building block in drug development.

Fragrances & Specialty Chemicals

Benzophenone is also valued in the fragrance industry as a fixative, stabilizing volatile aromatic compounds and prolonging scent longevity. Additionally, it is used in the production of dyes and other specialty chemicals.
