This chemical is primarily used in bioconjugation and protein labeling applications. It serves as a reactive ester that can efficiently attach to amine groups, making it valuable for modifying biomolecules like proteins, peptides, and antibodies. Its perfluorophenyl group enhances reactivity, enabling precise and stable conjugation under mild conditions. This compound is particularly useful in developing diagnostic tools, targeted drug delivery systems, and advanced research in proteomics. It also finds applications in surface functionalization for biosensors and nanomaterials, where controlled and specific biomolecule attachment is critical.
