Description

Trimethyl(Nonafluorobutyl)Silane is a specialized organofluorosilicon compound, recognized for its unique combination of a fluorinated alkyl chain and a trimethylsilyl group. This structure makes it a valuable intermediate and reagent for introducing fluorinated moieties into various molecular architectures. It is particularly sought after by industries requiring materials with enhanced surface properties, chemical resistance, or specific reactivity. Key sectors include advanced materials science, specialty chemical synthesis, and performance coatings.

Application

• Surface Modification Agent: Used to impart hydrophobic and oleophobic properties to glass, ceramics, and metals.
• Fluorinated Silicone Synthesis: Serves as a key building block for creating high-performance fluorosilicone oils, rubbers, and resins.
• Pharmaceutical & AgroChemical Intermediates: Acts as a versatile reagent for introducing the perfluorobutyl group into bioactive molecules to alter their lipophilicity and metabolic stability.
• Electronics & Semiconductor Processing: Employed in the formulation of specialty coatings and as a precursor in chemical vapor deposition (CVD) for low-surface-energy films.
• Specialty Additives: Incorporated into lubricants, paints, and sealants to enhance their chemical and thermal resistance.
• Analytical Chemistry: Utilized as a derivatization agent in gas chromatography for the analysis of specific compounds.

Storage

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