Product Detail:
Description

Implementation standard: Q/SEB003-2015

Chemical name: Lithium bis(trimethylsilyl)amide; Hexamethyldisilazane lithium salt CAS NO:4039-32-1

Molecular weight: 168.3332

Molecular formula: C6H18LiNSi2

Melting Point: 158-161 °C

Boiling Point: 120-125 °C (sublimes)

Solubility: Soluble in organic solvents such as THF, ether, and hexane

​Strong Base: LiHMDS is a strong base with a pKa of around 35. It is capable of deprotonating a wide range of acidic compounds.

Sterically Hindered: The bulky trimethylsilyl groups make LiHMDS selective in reactions, favoring deprotonation of less hindered sites.  

Sensitive to Air and Moisture: LiHMDS reacts readily with air and moisture, so it must be handled under anhydrous conditions.
