Used in Suzuki-Miyaura cross-coupling reactions as a stable and protected form of 4-pyridineboronic acid. Its MIDA protection allows for improved handling, storage, and compatibility with multi-step synthetic sequences. Commonly applied in pharmaceutical and agrochemical synthesis where controlled release of the boronic acid is beneficial. Also employed in the preparation of functionalized heterocyclic compounds for materials science and medicinal chemistry due to its stability and selective deprotection properties.
