Lithium Methoxide (LiOMe) 10% in Methanol Description:
Lithium Methoxide (LiOMe) (CAS: 865-34-9) is a mild base primarily used in organic synthesis, particularly in transesterifications. This reagent is currently available in a 2.2M methanol solution of LiOMe, making it easy to transfer from shipping containers to storage or reactors. When exposed to moisture, it reacts to form methanol and lithium hydroxide, causing the solution to become cloudy.
