Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where protection of amine functionalities is required. The tert-butyloxycarbonyl (Boc) group provides stability during multi-step reactions and can be selectively removed under mild acidic conditions, making it valuable in peptide and heterocyclic chemistry. The cyanobenzyl moiety can serve as a precursor for further functionalization, such as conversion to tetrazoles or carboxylic acids, useful in drug design for bioisosteric replacements or metabolic stability enhancement. Commonly employed in research settings for constructing complex molecules in medicinal chemistry.
