Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. It serves as a building block in medicinal chemistry due to its ability to form stable amide bonds and participate in cyclization reactions. Commonly employed in the preparation of heterocyclic compounds such as benzoxazoles and quinazolines, which are found in various drug candidates. Also utilized in research settings for the design of protease inhibitors and anti-cancer agents. Its methoxyamino group enhances binding selectivity in some enzyme inhibitor systems.
