Description

(Pentafluoroethyl)Trimethylsilane is a highly fluorinated organosilicon compound, recognized by the CAS registry number 124898-13-1. This specialty chemical is valued for its unique combination of a perfluoroalkyl group and a reactive silyl moiety, making it a versatile building block in advanced material synthesis. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for introducing fluorine-containing functional groups.

Application

• Pharmaceutical Intermediate: Used as a key fluorinating reagent or protecting group in the synthesis of active pharmaceutical ingredients (APIs) to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a precursor for creating novel fluorinated pesticides and herbicides, leveraging fluorine's ability to improve lipophilicity and target binding.
• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to surfaces (e.g., textiles, glass, semiconductors) through the formation of fluorosilane monolayers.
• Fluoropolymer & Elastomer Production: Acts as a monomer or cross-linking agent in the development of high-performance, chemically resistant fluorosilicone materials.
• Lithium-Ion Battery Electrolytes: Investigated as an electrolyte additive or co-solvent to improve thermal stability, voltage window, and cycle life of battery cells.
• Organic Synthesis Reagent: Employed in nucleophilic substitution and coupling reactions to introduce the pentafluoroethyl group into complex organic molecules.

Quality Control

Our (Pentafluoroethyl)Trimethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from strong bases and incompatible materials.
