This compound is widely used in the field of bioconjugation and protein labeling. It serves as an activated ester, facilitating the attachment of nonanoate groups to amino groups in proteins, peptides, or other biomolecules. This is particularly useful in modifying biomolecules for research, diagnostics, and therapeutic applications. It is also employed in the synthesis of polymers and materials where specific functionalization is required. Additionally, it plays a role in creating drug delivery systems by enabling the conjugation of active pharmaceutical ingredients to carriers or targeting moieties. Its reactivity and stability make it a valuable tool in organic synthesis and biochemical engineering.
