Chemical Intermediates Methyllithium Solution CAS 917-54-4

Products Description

What is Chemical intermediates Methyllithium solution CAS 917-54-4 ?

Methyllithium is a highly active organolithium reagent with a molecular formula of CH3Li and a molecular weight of 21.98. The pure compound is a colorless solid, and commercial formulations are typically ether solutions (e.g., diethyl ether, tetrahydrofuran), appearing as colorless to light melt brown transparent liquids. Its point is 70-71°C (pure form), and solution density is approximately 0.85 g/mL at 20°C.
Methyllithium liquid functions as a strong base and nucleophilic reagent. It reacts violently-even igniting spontaneously-upon contact with water, oxygen, or carbon dioxide, necessitating strict air and moisture exclusion during storage.
