4,4'-Dichlorobenzophenone, also known as benzophenone-4 or BP-4, is a chemical compound with the molecular formula C13H8Cl2O. It belongs to the group of benzophenone derivatives and is commonly used in various industries. Here are some of the effects and potential uses of 4,4'-Dichlorobenzophenone:UV Absorber: One of the primary uses of 4,4'-Dichlorobenzophenone is as a UV absorber. It has the ability to absorb ultraviolet (UV) radiation, specifically in the UVA range. This property makes it suitable for incorporation into sunscreen formulations and other personal care products to protect the skin and hair from harmful UV rays.Photostabilizer: 4,4'-Dichlorobenzophenone acts as a photostabilizer, meaning it helps to protect various substances from degradation caused by exposure to light. It is commonly used in the formulation of products such as plastics, coatings, and adhesives to prevent discoloration, photochemical reactions, and loss of physical properties.Polymer Additive: Due to its ability to absorb UV radiation and act as a photostabilizer, 4,4'-Dichlorobenzophenone is often added to polymer materials, such as plastics and resins. It helps to enhance the durability and lifespan of these materials by protecting them from the damaging effects of sunlight and other sources of UV radiation.Solvent: 4,4'-Dichlorobenzophenone has some solubility in organic solvents. This property makes it useful as a solvent or co-solvent in certain applications, such as the formulation of pharmaceuticals, dyes, and chemicals.Safety Considerations: While 4,4'-Dichlorobenzophenone has many applications, it is important to handle it with caution. It can be irritating to the skin, eyes, and respiratory system. Proper safety measures, including using appropriate personal protective equipment and working in a well-ventilated area, should be followed when handling this compound.In summary, 4,4'-Dichlorobenzophenone has several effects and applications, primarily as a UV absorber, photostabilizer, and polymer additive. It is commonly used in the formulation of sunscreen, personal care products, plastics, coatings, and adhesives. However, it is essential to consider the safety precautions when handling this compound to prevent any adverse effects on human health and the environment.
