In the intricate world of chemical synthesis and material science, certain compounds emerge as indispensable building blocks for advanced applications. 2-Hydroxy-2-methylpropiophenone, identified by CAS number 7473-98-5, stands out as a critical chemical intermediate, primarily recognized for its pivotal role as a UV photoinitiator. Its unique molecular structure enables it to initiate rapid polymerization upon exposure to UV light, making it a cornerstone in the development of UV-curable inks, coatings, and adhesives. As a prominent manufacturer and supplier in China, we are committed to providing this essential intermediate to global industries.

The Chemical Identity and Role

2-Hydroxy-2-methylpropiophenone is an organic compound with the molecular formula C10H12O2. Its structure features a propiophenone backbone with a hydroxyl group and two methyl groups on the alpha-carbon adjacent to the carbonyl. This specific arrangement is key to its function as a photoinitiator. When exposed to UV radiation, the molecule undergoes alpha-cleavage, a process that efficiently generates free radicals. These radicals then trigger the polymerization of monomers and oligomers in the formulation.

Key Properties Driving Its Utility

The efficacy of 2-hydroxy-2-methylpropiophenone CAS 7473-98-5 as a chemical intermediate for UV curing applications is attributed to several key properties:

  • Efficient Radical Generation: Its structure is optimized for efficient alpha-cleavage under UV light, leading to high radical quantum yields.
  • Solubility and Compatibility: It demonstrates good solubility in common UV-curable resins and monomers, facilitating easy integration into complex formulations.
  • Low Yellowing Characteristics: Unlike some other photoinitiators, it contributes minimally to yellowing in the cured polymer, preserving the aesthetic integrity of the final product. This is a critical factor for applications like clear coatings and white inks.
  • Versatile Applications: It serves as a vital intermediate in the synthesis of materials for various UV-curing applications, including printing inks, wood coatings, plastic coatings, adhesives, and certain types of photopolymers used in 3D printing.
