Frequent Uses

Grignard Reagents
Magnesium is a key component in the synthesis of Grignard reagents, which are essential for creating carbon-carbon bonds in organic synthesis.

Catalysis
Magnesium can catalyse various chemical reactions, such as the O-acylative cleavage of tetrahydrofuran, where they react with acyl chlorides in the presence of dry tetrahydrofuran to produce 4-chlorobutyl esters.

Reducing Agent
In some chemical processes, magnesium acts as a reducing agent, facilitating reactions by donating electrons.

Pyrotechnics
The high combustion temperature of magnesium makes it useful in pyrotechnic applications like flares and fireworks.
