Description

4-Chloro-5(3)-Methyl-3(5)-(Nonafluorobutyl)Pyrazole CAS NO 247220-82-2 is a specialized fluorinated pyrazole derivative, a high-value building block prized for its unique combination of a heterocyclic core and a perfluorinated alkyl chain. This compound matters for its ability to impart exceptional chemical stability, hydrophobicity, and lipophobicity to advanced materials and active ingredients. It is primarily needed by R&D and production teams in the agrochemical and pharmaceutical industries for developing novel active ingredients, as well as in materials science for creating specialty polymers and surface modifiers.

Application

• Agrochemical Intermediates: A key synthon for the development of next-generation herbicides and insecticides, leveraging the fluorinated moiety to enhance bioavailability and environmental persistence.
• Pharmaceutical Building Blocks: Used in medicinal chemistry research to create novel drug candidates, where the pyrazole ring and fluorine atoms can modulate biological activity and metabolic stability.
• Specialty Polymer Synthesis: Serves as a monomer or functionalizing agent for fluoropolymers, imparting oil, water, and stain resistance to high-performance coatings and materials.
• Liquid Crystal & Electronic Materials: Employed in the synthesis of fluorinated components for liquid crystal displays (LCDs) and dielectric materials due to its polarizability and thermal stability.
• Surface Modification Reagents: Used to create low-surface-energy coatings for textiles, membranes, and electronic components.
• Catalyst Ligand Precursors: The pyrazole nitrogen can coordinate to metals, making it a precursor for specialized ligands in catalytic systems.
