Description

2-Chloro-3',5'-Difluorobenzophenone is a high-purity, multi-functional benzophenone derivative serving as a critical synthetic intermediate in advanced organic chemistry. Its value lies in its unique halogenated and fluorinated structure, which enables precise molecular modifications essential for developing compounds with targeted properties. This product is primarily needed by R&D and production teams in the pharmaceutical and agrochemical industries for synthesizing active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a halogenated benzophenone core.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and pesticides, where the difluoro and chloro substituents contribute to biological activity.
• Material Science Research: Employed as a monomer or precursor in the development of specialty polymers, liquid crystals, and organic electronic materials.
• Organic Synthesis Reagent: Functions as a versatile electrophile or coupling partner in cross-coupling reactions (e.g., Suzuki, Heck) for constructing complex aromatic systems.
• Photoinitiator & UV Absorber Development: Serves as a structural component in the design of novel photoinitiators for coatings and UV-stabilizing additives due to the benzophenone moiety.
