(6-Methoxy-1,5-naphthyridin-4-yl)boronic acid is primarily used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed in the pharmaceutical industry to create complex organic compounds, including active pharmaceutical ingredients (APIs). The boronic acid group in the compound acts as a key functional group, enabling the formation of carbon-carbon bonds with aryl or vinyl halides in the presence of a palladium catalyst. This makes it valuable for constructing biaryl structures, which are common in many drugs and agrochemicals. Additionally, it may be utilized in the development of fluorescent probes or sensors due to the naphthyridine moiety, which can exhibit unique photophysical properties. Its application extends to materials science, where it can be incorporated into polymers or small molecules for advanced material design.
