Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of kinase inhibitors and other bioactive molecules. Its bromine functionality allows for further cross-coupling reactions, enabling structural diversification. The presence of a stereogenic center makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in biological activity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid pyridine core and modifiable hydroxyl group.
