In the realm of industrial chemicals, certain compounds stand out due to their versatile properties and broad applicability. 4-Chlorobenzophenone (CAS: 134-85-0) is one such compound, recognized for its significant contributions as both a photoinitiator and a crucial chemical intermediate across several key industries.

Understanding 4-Chlorobenzophenone: Properties and Structure

4-Chlorobenzophenone is an organic compound with the chemical formula C13H9ClO. Its molecular structure features a benzophenone core with a chlorine atom attached to one of the phenyl rings. This structure lends it specific chemical and physical properties that make it valuable in various applications. It typically appears as a white to off-white crystalline powder or flakes, with a melting point in the range of 75-77°C. With a purity of ≥99%, it is well-suited for demanding industrial processes.

Primary Role: Photoinitiator in UV Curing

One of the most prominent applications of 4-Chlorobenzophenone is its use as a photoinitiator, specifically a Type II free-radical initiator, in ultraviolet (UV) curing systems. In this capacity, it absorbs UV light, generating reactive species that initiate the polymerization of monomers and oligomers. This process is fundamental to the fast and efficient curing of:

  • UV-Curable Coatings: Used extensively in furniture, automotive, and electronics industries for protective and decorative finishes.
  • UV Inks: Essential for high-speed printing on various substrates in packaging, labels, and graphic arts.
  • Adhesives and Sealants: Providing rapid bonding and sealing solutions in manufacturing and construction.

Its performance is enhanced when used with amine synergists, and its low odor and good anti-yellowing properties make it a preferred choice for applications requiring high aesthetic quality and durability.

Vital as a Chemical Intermediate

Beyond its role in UV curing, 4-Chlorobenzophenone is highly valued as an intermediate in organic synthesis. Its reactive nature allows it to be a key building block in the production of:

  • Pharmaceuticals: It serves as a precursor in the synthesis of various active pharmaceutical ingredients (APIs), contributing to the development of new medicines.
  • Pesticides and Agrochemicals: It is an important component in the manufacturing of certain pesticides, aiding in crop protection and agricultural productivity.
  • Dyes and Pigments: Its chemical structure can be modified to create specialized dyes and pigments with enhanced properties.
