Description

Ammonium 8-Chlorohexadecafluoro-7-Methyloctanoate is a high-performance fluorinated ammonium salt, a key intermediate in advanced material synthesis. This compound is valued for its unique combination of a perfluorinated carbon chain and a reactive ammonium head group, which imparts exceptional surface activity and chemical resistance. It is primarily sought by manufacturers in the specialty chemical, polymer, and electronics industries for developing water- and oil-repellent coatings, surfactants for demanding environments, and as a building block for fluorinated polymers.

Application

• Fluorinated Surfactant & Emulsifier: Used in fire-fighting foams, coatings, and specialty cleaning formulations where extreme chemical and thermal stability is required.
• Polymer & Resin Modification: Serves as a key monomer or additive to introduce fluorinated segments, enhancing the hydrophobicity, oleophobicity, and durability of polymers.
• Surface Treatment & Coatings: A critical component in formulating high-performance water- and stain-repellent finishes for textiles, leather, and paper.
• Electronics Industry: Used in the production of fluorinated chemicals for electronics cleaning, etching solutions, and as a precursor for dielectric materials.
• Pharmaceutical & Agro-chemical Intermediates: Acts as a building block for synthesizing more complex fluorinated molecules with specific biological activity.
