Lanthanum (III) chloride hexahydrate(CAS: 17272-45-6)

Lanthanum (III) chloride hexahydrate is a white, crystalline solid with a molecular weight of approximately 385 g/mol. It is highly soluble in water, with a solubility of about 23 g/100 mL at 20°C. Chemically, it is moderately reactive with strong acids and bases. The hexahydrate form ensures stability and prevents dehydration. It is also known for its low toxicity and good water solubility, making it suitable for various applications.

Lanthanum (III) chloride hexahydrate is commonly synthesized by reacting lanthanum metal or lanthanum oxide with hydrochloric acid in an aqueous solution. The reaction is usually carried out under mild conditions, and the product is purified by filtration and drying. This method ensures high purity and yield, making it a preferred route for industrial production.

Lanthanum (III) chloride hexahydrate finds applications in various industries, including pharmaceuticals for its use as a dietary supplement and in the treatment of hyperparathyroidism. It is also used in the production of polymer stabilizers, gas sensors, and in the manufacturing of certain electronic components. Additionally, it plays a role in the development of new materials for energy storage and catalysis.

When handling Lanthanum (III) chloride hexahydrate, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and moisture. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
