4-Chlorobenzophenone

　　Main Uses

　　Photoinitiator: It is a commonly used photoinitiator in UV-curable coatings and inks. It can absorb ultraviolet light of specific wavelengths to generate active free radicals, initiating the polymerization of monomers such as acrylates, thereby achieving rapid curing of coatings and inks. It is widely used in fields such as plastic and metal overprint varnishes, paper coatings, offset inks, flexographic inks, and screen printing inks.

　　Pharmaceutical Intermediate: It is a key raw material for the synthesis of the drug fenofibrate, can also serve as an impurity reference standard for cetirizine, and is widely used in the synthesis of various other drugs.

　　Agrochemical Intermediate: It plays an important role in agrochemical synthesis and can be used to prepare pesticide formulations with insecticidal, fungicidal, and herbicidal activities.

　　Heat-Resistant Polymer Synthesis: It can be used to prepare high-performance engineering plastic modifiers, improving the heat resistance and mechanical properties of polymers.
