Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its alkyne functionality allows for efficient coupling reactions, such as click chemistry via copper-catalyzed azide-alkyne cycloaddition, enabling rapid assembly of complex structures for drug discovery. The tert-butyl carbamate (Boc) group serves as a protected amine, offering stability during synthetic transformations and easy deprotection under mild acidic conditions. This compound is valuable in building blocks for medicinal chemistry and in the preparation of labeled compounds for biochemical assays.
