Description

Perfluorodecanesulfonyl Fluoride is a high-value fluorinated organic building block characterized by its highly stable perfluorinated carbon chain and reactive sulfonyl fluoride group. This compound matters for its role as a critical precursor in synthesizing advanced perfluorinated surfactants, polymers, and surface modifiers, which are essential for creating oil-, water-, and stain-resistant properties. It is needed by R&D chemists and production specialists in the fluorochemical, pharmaceutical, and specialty materials industries seeking to develop high-performance coatings, fire-fighting foams, and novel bioactive molecules.

Application

• Key intermediate for the synthesis of perfluorooctanesulfonate (PFOS)-related substances and alternatives.
• Precursor for manufacturing fluorinated surfactants and emulsifiers used in specialty coatings and fire-fighting foams (AFFF).
• Building block for surface modification agents that impart oil, water, and stain repellency to textiles, carpets, and paper.
• Starting material in the production of ion-exchange membranes and other fluorinated polymers for electrochemical applications.
• Reagent for introducing the perfluorodecyl sulfonyl moiety into pharmaceutical and agrochemical candidates to alter bioavailability and metabolic stability.
• Used in research to develop fluorous-phase synthesis techniques and catalysts.
• Intermediate for creating anti-reflective coatings and other optical materials.

Quality Control

Our Perfluorodecanesulfonyl Fluoride is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, GC, and GC-MS, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, assay, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, ensuring traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and sources of ignition.
