Used in organic synthesis as a key intermediate for the preparation of complex molecules, particularly in the development of pharmaceuticals and agrochemicals. Its tributylstannyl group facilitates cross-coupling reactions, such as Stille coupling, enabling the formation of carbon-carbon bonds in the synthesis of thiazole derivatives. These derivatives are valuable in creating compounds with potential biological activity, including antimicrobial, antifungal, and anticancer agents. Additionally, it serves as a building block in materials science for designing functional materials with specific electronic or optical properties.
