Description

Heptadecafluorooctanesulfonic Acid Tetrabutylammonium Salt is a high-purity, perfluorooctanesulfonate (PFOS) derivative salt, valued for its role as a versatile fluorinated surfactant and phase-transfer catalyst. This compound is critical for applications requiring the unique properties of perfluorinated chains, such as extreme chemical stability, hydrophobicity, and oleophobicity. It is primarily needed by researchers and manufacturers in the electronics, specialty polymer, and advanced materials sectors for surface modification, electroplating, and as a key intermediate in fluorochemical synthesis.

Application

• As a phase-transfer catalyst in organic synthesis, particularly for fluorination reactions.
• As a key component in fluorosurfactant formulations for coatings and fire-fighting foams (where regulations permit).
• As a surface modifier to impart oil and water repellency to textiles, paper, and leather.
• In electronic chemicals for use in photoresists and anti-reflective coatings in semiconductor manufacturing.
• As a standard or reference material for analytical testing and environmental monitoring of perfluoroalkyl substances (PFAS).
• In academic and industrial R&D for studying the properties and applications of perfluorinated compounds.
