Synonyms: N-(Fmoc-oxy)succinimide
Fmoc-OSu (N-(Fmoc-oxy)succinimide) is an acylating agent that targets amino groups (-NH2). It can selectively protect the amino groups of amino acids by covalently binding with primary or secondary amines through nucleophilic substitution reactions. Fmoc-OSu forms a stable amide bond with the amino group to avoid side reactions of the amino group in peptide synthesis. It can also be used as a fluorescent labeling reagent to react with glycosylamines for efficient labeling of N-sugar chains. Fmoc-OSu can be used as an Fmoc protection strategy in peptide synthesis, and as a fluorescent labeling and analysis method for N-sugar chains .
