Active esters
Active ester reagents are reactive compounds widely used for bioconjugation, polymer functionalization, peptide coupling, and biomaterial engineering applications. These reagents readily react with primary amines to form stable amide bonds under mild conditions.
NSP offers a broad range of active ester compounds including NHS esters, sulfo-NHS esters, DBCO-NHS, biotin-NHS, fluorescent NHS reagents, and functional polymer active esters for drug delivery, click chemistry, and advanced biomedical research applications.
