Used in bioconjugation processes to link molecules such as peptides, proteins, or dyes to other compounds through amine-reactive chemistry. Commonly applied in the development of diagnostic probes, targeted drug delivery systems, and functionalized surfaces for biosensors. Its structure allows efficient coupling under mild aqueous conditions, making it suitable for labeling biomolecules without compromising their activity. Also utilized in cosmetic formulations for enhanced skin penetration, where it helps stabilize active ingredients and improve delivery into deeper skin layers.
