Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of targeted drug delivery systems and prodrugs. Its functional groups allow for selective conjugation with other bioactive molecules, making it valuable in medicinal chemistry for creating hydrazide-based linkers. Commonly applied in the preparation of antibody-drug conjugates (ADCs) and in bioconjugation techniques where controlled release and stability are required. Also utilized in research settings for labeling and modifying peptides or proteins due to its reactive hydrazine moiety protected with a Boc group, enabling mild deprotection conditions.
