Used primarily as a key intermediate in pharmaceutical synthesis, this compound enables the formation of complex heterocyclic structures through Suzuki-Miyaura cross-coupling reactions. Its boronate ester group facilitates carbon-carbon bond formation under mild conditions, making it valuable in the development of bioactive molecules and drug candidates. It is particularly useful in constructing benzoxazine-based scaffolds, which are found in compounds with potential neurological and anti-inflammatory activity. The reagent supports efficient, selective coupling in late-stage functionalization of drug molecules, enhancing structural diversity in medicinal chemistry research.
