Used primarily as a key intermediate in pharmaceutical synthesis, this compound enables the preparation of bioactive molecules through Suzuki-Miyaura cross-coupling reactions. Its boronate ester functionality allows for efficient carbon-carbon bond formation, making it valuable in the development of drug candidates targeting central nervous system disorders and inflammatory diseases. The protected carboxylic acid groups provide selective reactivity, facilitating stepwise derivatization in complex molecule assembly. It is especially useful in medicinal chemistry for constructing isoquinoline-based scaffolds found in therapeutic agents.
