Used as a dehydrating agent in organic synthesis, it effectively removes water from reactions, facilitating the formation of anhydrous conditions. It is also employed in the protection of carbonyl groups, particularly in the synthesis of sensitive compounds where moisture must be avoided. Additionally, it serves as a solvent in various chemical processes, offering stability and compatibility with a wide range of reactants. Its role in acetal formation is crucial for protecting aldehydes and ketones during complex synthetic sequences.
