Used as a drying agent in organic synthesis due to its high affinity for water, effectively removing trace moisture from solvents and reaction mixtures. Commonly employed in laboratory settings to purify liquids by dehydration. Also serves as a magnesium source in chemical reactions, especially in the preparation of catalysts and coordination compounds. In industrial processes, it functions as a desiccant and is utilized in the production of fertilizers, textiles, and paper. Additionally, finds use in pharmaceutical formulations and as a component in bath salts for therapeutic purposes.
