Description

4-Bromo-5-Methyl-3-[1,2,2,2-Tetrafluoro-1-(1,1,2,2,3,3,3-Heptafluoropropoxy)Ethyl]-1H-Pyrazole is a highly fluorinated pyrazole derivative, a sophisticated chemical building block prized for its unique structural and electronic properties. This compound is critical for advanced research and development, particularly in the design of novel active ingredients. It is primarily sought by the agrochemical and pharmaceutical industries for use as a key intermediate in the synthesis of next-generation crop protection agents and specialty fluorinated pharmaceuticals.

Application

• Agrochemical Intermediate: A key synthon for the development of novel herbicides, fungicides, and insecticides, leveraging the stability and lipophilicity imparted by the perfluoroalkyl ether moiety.
• Pharmaceutical Research: Serves as a versatile building block in medicinal chemistry for creating fluorinated drug candidates, where fluorine atoms can enhance metabolic stability, bioavailability, and binding affinity.
• Material Science Precursor: Used in the synthesis of specialized fluorinated polymers, coatings, and liquid crystals that require specific thermal and chemical resistance properties.
• Chemical Synthesis: Acts as a reactive intermediate for introducing complex fluorinated groups into target molecules via further functionalization of the pyrazole ring or the bromine substituent.
