Description

p-(Pentadecafluoroheptyl)Benzenesulphonyl Chloride CAS NO 25444-35-3 is a high-value fluorinated aromatic sulfonyl chloride derivative, serving as a critical building block for advanced material synthesis. Its unique structure, featuring a long perfluoroalkyl chain, imparts exceptional hydrophobicity, oleophobicity, and chemical stability to downstream products. This specialty intermediate is essential for manufacturers in the surfactants, polymer modification, and pharmaceutical/agrochemical sectors seeking to incorporate high-performance fluorinated properties.

Application

• Fluorinated Surfactant & Polymer Synthesis: A key precursor for creating high-performance, low-surface-tension surfactants and fluoropolymers with oil, water, and stain resistance.
• Surface Modification Agents: Used to manufacture coatings and treatments for textiles, paper, and membranes to confer durable hydrophobic and oleophobic characteristics.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of bioactive molecules where the perfluoroalkyl group can enhance metabolic stability and membrane permeability.
• Advanced Material Research: Serves as a versatile reagent in R&D for developing novel fluorinated liquid crystals, electrolytes, and other functional materials.
• Lithography and Electronics: Potential use in photoresists and electronic chemicals for the semiconductor industry due to its chemical and thermal stability.
