Used in organic synthesis as a building block for pharmaceuticals, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its boronic acid group enables efficient carbon-carbon bond formation, making it valuable in drug discovery and development. The thiazolidine moiety can contribute to biological activity, allowing incorporation into molecules with potential antimicrobial or antidiabetic properties. Also applied in the synthesis of sensors and functional materials due to its selective binding and reactivity.
