Used as a key reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a boronate ester that enables the formation of carbon-carbon bonds, especially in the construction of complex molecules such as pharmaceuticals, agrochemicals, and functional materials. Its stable pyran-protected structure allows for selective transformations and improved handling compared to more sensitive boronic acids. Commonly employed in late-stage functionalization due to its compatibility with various functional groups and mild reaction conditions.
