Description

Perfluoropentane-1-Sulphonyl Fluoride is a high-value perfluorinated sulfonyl fluoride building block, essential for introducing the perfluoroalkylsulfonyl group into target molecules. Its primary value lies in its role as a key intermediate for synthesizing advanced materials and specialty chemicals with unique surface properties and stability. This compound is particularly needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced polymer industries for creating novel surfactants, electrolytes, and functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly for introducing fluorinated groups to alter metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key precursor for creating novel fluorinated pesticides and herbicides with enhanced environmental persistence and efficacy.
• Polymer & Material Science: A crucial monomer or modifier for producing high-performance fluoropolymers, ion-exchange membranes (e.g., for fuel cells), and specialty surfactants with exceptional chemical and thermal resistance.
• Lithium Battery Electrolytes: Employed in the development of novel lithium salts (e.g., LiPFSI analogs) for next-generation lithium-ion batteries to improve conductivity and stability.
• Surface Modification Agent: Used to create low surface energy coatings, imparting water, oil, and stain repellency to textiles, electronics, and industrial components.
• Organic Synthesis Building Block: Acts as a versatile reagent in nucleophilic substitution reactions to install the perfluoropentylsulfonyl moiety, a valuable handle in medicinal and materials chemistry.

Quality Control

Our Perfluoropentane-1-Sulphonyl Fluoride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee it meets your specific R&D or production requirements.

Storage

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