Frequently asked questions
What is triisopropylsilane (CAS 6485-79-6) commonly used for?
Triisopropylsilane is primarily used as a carbocation scavenger and hydride donor in organic synthesis, particularly in trifluoroacetic acid (TFA) cleavage and deprotection cocktails in peptide synthesis and as a reducing agent in ionic hydrogenation reactions. It is also used as a hydrogen donor in photochemical reductions.
What is the molecular formula and molecular weight of triisopropylsilane?
The molecular formula is C₉H₂₁Si, and the molecular weight is 157.35 g/mol.
How should triisopropylsilane be stored?
Store in a tightly sealed container at ambient temperature, away from oxidizing agents and moisture. Avoid exposure to air to prevent peroxide formation.
What purity grades of triisopropylsilane does Molekula offer?
Molekula supplies triisopropylsilane in analytical grade (≥98% purity) and synthesis grade (≥97% purity). Higher purity or custom specifications may be available upon request.
Can Molekula supply triisopropylsilane in bulk quantities?
Yes, we offer bulk packaging options (e.g., 5kg, 25kg drums, or ISO containers) for triisopropylsilane. Minimum order quantities and pricing depend on the grade and application.
What documentation is provided with a triisopropylsilane order?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and batch-specific documentation (e.g., purity, impurities profile). Custom packaging labels are also provided upon request.
