Used in peptide synthesis and pharmaceutical development as a protected amino acid building block. The Boc (tert-butoxycarbonyl) group provides temporary protection for the amine functionality, allowing selective reaction at the carboxylic acid site. This compound is particularly useful in the preparation of heterocyclic-containing peptides and bioactive molecules where the isonicotinic acid moiety can act as a structural or functional component. Its design supports solid-phase and solution-phase synthesis strategies, making it valuable in medicinal chemistry for constructing drug candidates targeting enzymes and receptors.
