Magnesium Chloride Hexahydrate is an inorganic compound with the chemical formula MgCl₂·6H₂O and CAS Number 7791-18-6. It is commonly supplied as a colourless to white crystalline solid or flakes and is highly soluble in water. The compound is the hydrated form of Magnesium Chloride and may absorb moisture from the surrounding environment due to its hygroscopic properties.

Magnesium Chloride Hexahydrate is valued as a source of magnesium and chloride ions in aqueous solutions and chemical reactions. Common laboratory applications include the preparation of magnesium-containing solutions, buffer preparation, microbiological culture media, biochemical experiments, analytical chemistry procedures, and research involving magnesium-dependent enzymes.

Its high water solubility and ability to provide magnesium ions make Magnesium Chloride Hexahydrate useful in biochemistry, microbiology, inorganic chemistry, and general laboratory research. It may also be used in specialised chemical formulations, educational experiments, and applications requiring a soluble magnesium salt. The appropriate grade, purity, and hydration form should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Magnesium Chloride Hexahydrate is generally considered a low-hazard chemical when handled appropriately. However, contact with the eyes may cause irritation, and inhalation of dust should be avoided. Use appropriate personal protective equipment, including laboratory gloves and safety goggles. Store in a tightly closed container in a cool, dry place to minimise moisture absorption. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
