What is Benzophenone Cas No.: 119-61-9 ?

Benzophenone is an organic compound with the chemical formula C13H10O. It’s a white crystalline flakes or white crystalline powder with a rose-like odor. It is soluble in ethanol, ether, chloroform and other organic solvents and monomers, insoluble in water. Benzophenone is used mainly as a precursor to other organic compounds and as a photoinitiator in UV-curing applications. We also used it in the production of plastics, perfumes, and pharmaceuticals. Additionally, it’s known for its ability to absorb ultraviolet (UV) light, making it useful in sunscreen formulations to protect the skin from UV radiation.

Main Applications:

 

1. UV Stabilizer in Plastics and Coatings: We can use benzophenone as a UV stabilizer in various plastic products, coatings, and paints. It absorbs ultraviolet (UV) light, preventing the degradation of the material caused by exposure to sunlight. This property is crucial for prolonging the life of products such as plastics, resins, and coatings, which are susceptible to UV-induced damage.
2. Fragrance and Flavoring Agent: In the fragrance industry, we can use benzophenone as a fixative, which helps in preserving the scent of perfumes. It is also utilized in flavorings due to its sweet, floral aroma, contributing to the stability and longevity of flavors in food and beverages.
3. Photoinitiator in Photochemistry: Benzophenone acts as a photoinitiator in photochemical reactions. When exposed to UV light, it can generate free radicals. It is essential for initiating polymerization processes in the production of various plastics and resins.
4. Pharmaceutical and Cosmetic Ingredient: We can find benzophenone derivatives in sunscreen products as active ingredients that protect the skin from harmful UV rays. We also can use it in the formulation of certain drugs and cosmetics for their UV-absorbing properties.
5. Organic Synthesis: Benzophenone is a versatile intermediate in organic synthesis. We use it to produce other chemicals, including benzpinacol, diphenylmethanol, and benzophenone derivatives, which are valuable in pharmaceuticals and agrochemicals.
6. Analytical Chemistry: In analytical chemistry, we use benzophenone as a reference standard and in the preparation of calibration curves for various analytical techniques.

Safety and Handling:

We should handle benzophenone with care. It can cause skin and eye irritation, and prolonged exposure may lead to more severe health effects. We should take proper safety measures, such as wearing protective gear and working in well-ventilated areas when dealing with this chemical.

Storage:

Stored in cool, dry and well-ventilated warehouse, to protect from fire and heat sources.
