This chemical is primarily used in organic synthesis as a reagent for the introduction of the 4-(ethoxycarbonyl)phenyl group into various organic molecules. It is particularly valuable in cross-coupling reactions, such as the Negishi coupling, where it facilitates the formation of carbon-carbon bonds. Its application is common in the synthesis of complex organic compounds, including pharmaceuticals, agrochemicals, and advanced materials. The solution form ensures ease of handling and precise control over reaction conditions, making it a versatile tool in modern synthetic chemistry. Additionally, it is employed in the development of liquid crystals and other functional materials due to its ability to modify molecular structures effectively.
