It is useful in polymer coupling to proteins, because it may lead to a better selectivity among all the amino groups present in a protein, thus yielding less heterogeneous PEG-protein conjugates mixture because only the most nucleophilic and solvent exposed amines can react. ; 9) Synonym: N-[[(2,5-Dioxo-1-pyrrolidinyl)oxy]carbonyl]-β-alanine 2,5-Dioxo-1-pyrrolidinyl Ester;
