Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its boronic acid group enables carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development. The pyrrolidinyl ethoxy phenyl moiety enhances solubility and binding properties, useful in designing bioactive molecules. Also applied in materials science for creating functionalized organic frameworks and sensors.
