Gadolinium(III) chloride hexahydrate(CAS: 13450-84-5)

Gadolinium(III) chloride hexahydrate is a white crystalline solid with a molecular weight of approximately 456.03 g/mol. It is slightly soluble in water and reacts with strong bases to form hydroxides. The compound is stable under normal conditions but should be stored in a dry place to prevent hygroscopy.

Gadolinium(III) chloride hexahydrate is typically synthesized by reacting gadolinium(III) oxide (Gd2O3) with hydrochloric acid (HCl) in the presence of water. The reaction is exothermic and should be carried out in a well-ventilated area with appropriate safety measures to handle the generated heat and gaseous HCl.

Gadolinium(III) chloride hexahydrate is widely used in the pharmaceutical industry for magnetic resonance imaging contrast agents. It is also used in the production of semiconductors, sensors, and polymers. Additionally, it is employed in the development of luminescent materials and catalytic applications.

When handling Gadolinium(III) chloride hexahydrate, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Ensure the work is conducted in a well-ventilated area or a fume hood. In case of a spill, immediately clean it up with appropriate absorbent materials and follow the safety data sheet (SDS) guidelines for further disposal. Storage should be in a dry, cool, and well-ventilated area to prevent hygroscopy and potential hazards.
