Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of tyrosine kinase inhibitors and other biologically active molecules. Its alkyne functionality allows for use in click chemistry reactions, especially copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient conjugation in drug discovery and bioconjugation applications. The tert-butyl carbamate (Boc) group serves as a protected amine, making it valuable in multi-step organic synthesis where selective deprotection is required. Commonly employed in the development of targeted cancer therapies and diagnostic probes due to its stability and reactivity profile.
