Description

2,4-Dimethylbenzophenone CAS NO 1140-14-3 is a specialized aromatic ketone derivative of benzophenone, characterized by its two methyl substituents on the phenyl ring. This structural modification makes it a valuable intermediate and functional component in advanced organic synthesis and material science applications. It is essential for manufacturers and R&D facilities in the pharmaceutical, agrochemical, and polymer industries seeking to develop or produce high-performance compounds.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and other complex organic molecules.
• Photoinitiator Component: Used in the formulation of UV-curable inks, coatings, and adhesives, where it contributes to the polymerization process upon light exposure.
• Agrochemical Synthesis: Serves as a precursor in the manufacturing of certain herbicides, pesticides, and plant growth regulators.
• Polymer Additive: Acts as a light stabilizer or a synergist in plastic and resin formulations to enhance durability against UV degradation.
• Organic Synthesis Reagent: Employed in research laboratories for Friedel-Crafts acylation and other reactions to introduce the benzophenone moiety into target molecules.
• Fragrance and Flavor Ingredient: Used in a limited capacity as a fixative or a component in the synthesis of aroma chemicals.
