Sodium Bis(Trimethylsilyl)Amide (1070-89-9)

Sodium Bis(Trimethylsilyl)Amide (NaHMDS) is a strong, non-nucleophilic base with the chemical formula C6H18NNaSi2 and molecular weight 183.38 g/mol. It is commonly supplied as a colorless solution in organic solvents such as THF or toluene, though it may also appear as a solid. It is highly moisture-sensitive and reacts with water and air.
In terms of uses and applications, Sodium Bis(Trimethylsilyl)Amide is widely used in organic synthesis and pharmaceutical manufacturing for deprotonation reactions and generation of enolates, carbanions, and other reactive intermediates. It is valuable in alkylation, acylation, and condensation reactions. It is also used in the preparation of heterocycles and active pharmaceutical ingredients. In research laboratories, it serves as a strong base where minimal nucleophilic side reactions are desired. Additionally, it is used in fine chemical production requiring precise, moisture-free reaction conditions.
