3-Acetamidophenylboronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for forming carbon-carbon bonds, making it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. It serves as a key intermediate in the synthesis of complex organic molecules due to its boronic acid group, which facilitates the coupling process. Additionally, it is employed in the development of sensors and diagnostic tools, as boronic acids can selectively bind to diols and sugars, enabling applications in glucose monitoring and other biochemical assays. Its role in medicinal chemistry is also notable, as it is used to create compounds with potential therapeutic properties.
