This organozinc reagent, 5-(1,3-Dioxolan-2-yl)-2-thienylzinc bromide solution (0.5 M in THF), is primarily used in organic synthesis for Negishi cross-coupling reactions. It serves as a versatile intermediate for introducing a protected 5-formylthiophen-2-yl group into various organic molecules, which can be deprotected to yield the corresponding aldehyde. Its applications are significant in the development of pharmaceuticals, agrochemicals, and advanced materials, particularly in constructing complex heterocycles essential for drug discovery and material science. The solution form ensures safe handling, stability, and precise dosing in reactions, making it invaluable for both research and industrial processes.
