Tris(trimethylsilyl)silane (TTMSS) Organosilicon Reagent with ≥99% Purity as Clear Colorless Liquid for Moisture Sensitive Applications

Tris(trimethylsilyl)silane (TTMSS) — Description & Specification

Tris(trimethylsilyl)silane (often abbreviated TTMSS) is an organosilicon compound (a silicon hydride functionalized with trimethylsilyl groups). It is commonly used as a silicon/vinylic reagent and/or silylation precursor in chemical synthesis, especially where controlled introduction of silyl groups or silicon-containing fragments is required.

Specifications 

Key Features

• Organosilicon reagent with three trimethylsilyl (TMS) groups on a central silicon framework.
• Often used to:
  • introduce silyl functionality in organic synthesis,
  • serve as a silicon-transfer reagent,
  • enable silicon-containing intermediates under inert conditions.
• Moisture/air sensitive behavior is typical for many TMS-containing reagents, requiring careful handling.

Applications 

Storage Recommendations

Because TTMSS is generally moisture/air sensitive:

• Keep tightly sealed at all times.
• Use desiccated conditions (dry glovebox or dry-line transfer if required).
• Protect from light/heat as applicable.
• Minimize exposure time to ambient atmosphere; use dry syringes or transfer techniques.
