Used as a powerful desiccant for removing trace amounts of water from gases and organic solvents due to its strong hygroscopic nature. Commonly employed in analytical chemistry to ensure moisture-free environments during sensitive reactions or measurements. Also utilized in the preparation of dry atmospheres in laboratory equipment and sealed systems. Its high efficiency in water absorption makes it suitable for drying air in specialized instrumentation where extreme dryness is required. Handle with care due to its strong oxidizing properties, especially in contact with organic materials.
