Description

3-(Undecafluoro-1-Pentyl)-5-(Methyl)Pyrazole is a specialized fluorinated pyrazole derivative, a high-value intermediate prized for its unique combination of a heterocyclic core and a perfluorinated alkyl chain. This structure imparts exceptional chemical stability, hydrophobicity, and oleophobicity, making it a critical building block for advanced material science. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and high-performance materials sectors for synthesizing novel compounds with tailored surface properties and bioactivity.

Application

• Pharmaceutical Intermediate: Used in the research and synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring enhanced metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key precursor for developing next-generation herbicides, fungicides, and insecticides with improved rainfastness and environmental persistence.
• Fluorinated Surfactants & Polymers: A crucial monomer for creating specialty surfactants, coatings, and polymers that demand extreme chemical resistance, low surface energy, and anti-stick properties.
• Liquid Crystal & Electronic Materials: Employed in the development of fluorinated liquid crystals and organic electronic materials for displays and semiconductor applications.
• Catalyst Ligand Modification: Used to synthesize fluorinated ligands for catalysts, enhancing their solubility in fluorous phases for specialized separation processes.
• Surface Modification Agent: Applied to modify material surfaces to achieve oil-, water-, and stain-repellent characteristics.
