Triisopropylsilane (TIPS) is a vital chemical compound with diverse applications in specialized fields such as peptide synthesis and advanced organic chemistry. As a manufacturer and supplier of high-purity chemicals, we understand the importance of providing detailed information about our products to facilitate their effective use. This guide delves into the properties, applications, and procurement considerations for Triisopropylsilane (CAS: 6485-79-6).

Key Properties and Characteristics:

  • Appearance: Clear liquid.
  • Chemical Formula: C9H22Si.
  • Molecular Weight: 158.36 g/mol.
  • Purity: Typically ≥99.0% by Gas Chromatography (GC).
  • Boiling Point: Approximately 166-178 °C.
  • Flash Point: Around 35-37 °C, indicating flammability.

Primary Applications:

The most prominent application of Triisopropylsilane is in Solid-Phase Peptide Synthesis (SPPS). Here, it acts as a potent carbocation scavenger. During the cleavage and deprotection steps of SPPS, strong acids are used, which can generate reactive carbocations. These carbocations can cause unwanted side reactions by attacking the peptide chain. Triisopropylsilane efficiently neutralizes these carbocations by donating a hydride ion, thus protecting the peptide and ensuring higher purity and yield. This makes it an indispensable reagent for peptide manufacturers and researchers.

Furthermore, Triisopropylsilane finds utility in Organic Synthesis. It functions as a mild reducing agent, suitable for delicate reductions where harsher reagents might cause degradation. Its sterically hindered nature also makes it valuable in selective silylation reactions, serving as a protecting group reagent for alcohols, amines, and thiols. This versatility makes it a sought-after chemical for academic research and the development of new synthetic methodologies.

Procurement Considerations:

When sourcing Triisopropylsilane, it is crucial to partner with a reliable manufacturer and supplier. Key considerations include:

  • Purity: Always verify the purity specifications, typically confirmed by GC analysis. High purity (≥99.0%) is essential for predictable and successful synthetic outcomes.
  • Packaging: Triisopropylsilane is commonly supplied in drums or smaller containers suitable for laboratory and industrial use. Storage under nitrogen is often recommended due to its reactivity.
  • Safety: As a flammable liquid with a relatively low flash point, appropriate handling and storage precautions are necessary. Refer to the Safety Data Sheet (SDS) for detailed information.
  • Supplier Reliability: Choose a supplier with a proven track record for quality, consistency, and timely delivery. Manufacturers offering technical support can also be highly beneficial.
