Description

Tri-n-Propylsilane is a versatile organosilicon compound, a clear, colorless liquid characterized by its reactive silicon-hydride (Si-H) bond. This functional group makes it a valuable reagent and intermediate in advanced organic synthesis and materials science. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as hydrosilylation, surface modification, and as a precursor for more complex silicon-containing molecules.

Application

• Hydrosilylation Reactions: Acts as a key reagent for the addition of Si-H bonds across unsaturated carbon-carbon bonds (alkenes, alkynes) to create functionalized organosilicon compounds.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces (e.g., silica, glass, metals) with propyl groups, altering surface properties like hydrophobicity, adhesion, and compatibility.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block in the synthesis of active ingredients and complex molecules requiring silicon incorporation.
• Polymer & Material Science: Employed as a cross-linking agent or monomer in the production of silicone polymers, resins, and advanced hybrid materials.
• Semiconductor & Electronics Manufacturing: Used in chemical vapor deposition (CVD) processes as a silicon source for thin films and coatings.
• Laboratory Reagent: A specialized reducing agent and silicon source in research-scale organic and organometallic synthesis.

Quality Control

Our Tri-n-Propylsilane is produced and tested under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure it meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and key physical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, open flames, and oxidizing agents.
