DNP-PEG3-Azide（Cat No.:I015856）is a heterobifunctional polyethylene glycol derivative incorporating a 2,4-dinitrophenyl (DNP) group and a terminal azide, linked by a PEG₃ spacer. The DNP group functions as a hapten or antigenic determinant, making it useful in immunology studies, antibody generation, and assay development. The azide terminus enables efficient bioorthogonal “click” chemistry reactions, including copper-catalyzed or strain-promoted cycloadditions, for site-specific conjugation. The PEG₃ spacer enhances solubility, flexibility, and reduces steric hindrance. This reagent is highly versatile for bioconjugation, immunological assay design, and functional material development.
