2-Anthraceneboronic acid is primarily utilized in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed to form carbon-carbon bonds, making it valuable in the production of complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials. The compound's anthracene moiety can also serve as a fluorescent tag, enabling its use in biochemical assays and imaging studies to track molecular interactions or localization within biological systems. Additionally, its boronic acid group allows for applications in sensing and molecular recognition, particularly in the detection of sugars and other diol-containing compounds. This makes it a useful component in the development of biosensors and diagnostic tools.
