Used as a powerful drying agent (desiccant) in laboratory settings due to its strong affinity for water. It is especially effective in removing trace moisture from gases and organic solvents. Commonly employed in analytical chemistry for the preparation of dry environments in desiccators, drying tubes, and storage containers. Also utilized in the synthesis of moisture-sensitive compounds where complete dryness is critical. Additionally, it serves as an absorbent for water produced during the combustion of samples in the determination of carbon and hydrogen content in organic compounds. Its high efficiency makes it suitable for applications requiring deep dehydration, though care must be taken due to its strong oxidizing properties.
