Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in creating compounds with potential anticancer and anti-inflammatory properties. Commonly employed in medicinal chemistry for constructing isoquinoline-based scaffolds, which are prevalent in drug discovery programs targeting neurological disorders and oncology. Also utilized in research settings to develop novel receptor modulators due to the bromine handle enabling further functionalization via cross-coupling reactions.
