Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors, antiviral agents, and neuronal nitric oxide synthase (nNOS) inhibitors for CNS disorders such as epilepsy, neuroprotection, and stroke. It also serves in the preparation of bioactive molecules with potential anti-inflammatory and anticancer properties. Its ability to cross the blood-brain barrier well makes it valuable as a starting material for designing brain-targeted therapeutics. Commonly employed in medicinal chemistry research for scaffold modification in drug discovery programs. Additionally, it finds use in the creation of fluorescent probes and dyes due to its favorable electronic properties.
