Used as a water scavenger in esterification and acetalization reactions, helping to drive equilibrium toward product formation by removing water. Commonly employed in the synthesis of fragrances, flavors, and pharmaceuticals where moisture-sensitive intermediates are involved. Acts as a methylating agent in organic synthesis, particularly for introducing methoxy groups. Also utilized in the preparation of enol ethers and acetals, which serve as protecting groups or reactive intermediates in multi-step syntheses. Its ability to generate acetic acid upon hydrolysis makes it useful in controlled acid-release systems.
