Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and kinase inhibitors. Its aldehyde and amino functional groups allow for versatile reactivity, enabling Schiff base formation and heterocycle construction. Commonly employed in medicinal chemistry for building nitrogen-containing heterocyclic compounds. Also utilized in the preparation of fluorescent probes due to its ability to form conjugated systems upon condensation reactions. Its bromine substituent facilitates further cross-coupling reactions, making it valuable in structure-activity relationship (SAR) studies during drug discovery.
