Beschreibung

Allgemeine Beschreibung

Magnesium is the most common mineral found in the human body. It is a cofactor for more than 300 enzymes and is known to regulate physiological functions like blood pressure, muscle contraction, and neuromuscular conduction. It can be used in the preparation of many biomaterials with biomedical applications. Magnesium is widely used in the organic synthesis as an organomagnesium compound viz Grignard reagent.

Anwendung

Magnesium can be used:

• To prepare 1,3-bis[2-(3-n-dodecylthienyl)]azulene, applicable as an acid sensor material.
• As a catalyst in the cleavage of tetrahydrofuran to 4-chlorobutyl esters.
• To prepare copper-based composite materials with improved mechanical properties.
