- Trimethylsilanol sodium salt

Organic Synthesis Reagent
Sodium trimethylsilanolate serves as a strong base in various organic reactions. Its sterically hindered nature can be advantageous in promoting specific transformations while minimising side reactions.
Silane Chemistry
As a salt of a silanol, it can participate in reactions involving silicon-centred species, acting as a source of the trimethylsilanolate anion for further derivatisation or functionalisation.
Deprotonation Agent
Its strong basicity allows for the deprotonation of relatively acidic protons, facilitating reactions such as alkylations, acylations, and condensations in organic synthesis.
