Description

1,1,2,2,4,5,5-Heptafluoro-3-oxapent-4-enyl(trimethyl)silane is a high-value organofluorine silane intermediate, engineered for advanced material synthesis. This compound is critical for introducing both fluorinated and silylated functionalities in a single step, enabling the development of novel materials with tailored surface properties and enhanced performance. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating high-performance coatings, adhesives, and active ingredients.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated drug candidates to improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key building block for creating advanced, weather-resistant pesticides and herbicides with fluorinated motifs.
• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to glass, metals, and polymers for anti-stain and easy-clean coatings.
• Fluorinated Silicone Precursor: A critical monomer for synthesizing specialty fluorosilicone elastomers and oils with exceptional chemical and thermal resistance.
• Adhesive & Sealant Formulation: Enhances the adhesion and environmental durability of high-performance sealants, particularly in automotive and aerospace applications.
• Lithography and Semiconductor Processing: Acts as a surface conditioning agent or a precursor in the deposition of low-k dielectric films in microelectronics fabrication.

Quality Control

Every batch of our 1,1,2,2,4,5,5-Heptafluoro-3-oxapent-4-enyl(trimethyl)silane is produced and tested under a strict quality management system. We guarantee high purity and lot-to-lot consistency through advanced analytical techniques including GC, NMR, and FTIR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to ensure it meets your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and incompatible with strong bases/alkalis and fluorides; keep away from such materials. Use under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage or after opening to maintain purity.
