Used as a source of magnesium in chemical synthesis and laboratory applications, particularly in buffer solutions for molecular biology techniques such as DNA and RNA electrophoresis. Serves as a catalyst or reagent in organic reactions, including condensation and esterification processes. Employed in the textile industry for dyeing and printing fabrics due to its mild acidity and solubility. Also utilized in the preparation of magnesium-containing materials and ceramics. Its hydrate form provides stability and ease of handling in moisture-controlled environments.
