Description

4-Chloro-5-Methyl-3-(1,1,2,2,3,3,4,4,5,5,6,6,6-Tridecafluorohexyl)-1H-Pyrazole CAS NO 244022-66-0 is a high-value fluorinated pyrazole derivative, a key building block in advanced material science and pharmaceutical research. Its unique structure, featuring a long perfluoroalkyl chain, imparts exceptional hydrophobicity, oleophobicity, and chemical stability, making it a critical intermediate for synthesizing specialty compounds. This product is primarily targeted at R&D and production teams in the agrochemical, pharmaceutical, and specialty polymer industries seeking to incorporate fluorinated motifs for enhanced performance.

Application

• Agrochemical Intermediates: Serves as a key precursor for novel herbicides and pesticides, where the fluorinated side chain can improve bioavailability and environmental persistence.
• Pharmaceutical Research: Used in medicinal chemistry to develop new active pharmaceutical ingredients (APIs), particularly for candidates requiring lipophilicity and metabolic stability.
• Specialty Polymer & Material Science: Acts as a monomer or modifier for creating fluorinated polymers, coatings, and surfactants with superior water and oil repellency (stain resistance).
• Liquid Crystal & Electronic Materials: Employed in the synthesis of fluorinated components for liquid crystal displays (LCDs) and dielectric materials.
• Surface Modification Agents: Used to functionalize surfaces, providing low surface energy characteristics essential for anti-fouling or easy-clean applications.
• Chemical Synthesis Building Block: Provides a versatile scaffold for further functionalization in organic synthesis, enabling the creation of complex fluorinated molecules.
