Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting inflammatory and autoimmune diseases. It serves as a protecting group reagent in organic synthesis, enabling selective reactions at other functional sites in complex molecules. Commonly employed in the preparation of bioactive benzimidazole derivatives, including antiviral and antiparasitic agents. Its stability under various reaction conditions makes it valuable in multi-step synthetic routes, especially in medicinal chemistry research and development.
