    Citraconic Anhydride 正品
    产地: Pierce
    货号: 20907
    规格: 100g
    名称: Citraconic Anhydride 
    Thermo Scientific Pierce Citraconic Anhydride reacts with primary amines to to form an amide bond with a terminal carboxyl group. This modification can be reversed using acidic conditions (pH 3-4) or with hydroxylamine.
    Citraconic Anhydride (2-methylmaleic anhydride) is used to block primary amine groups at alkaline pH values (pH 7-9). At acidic pH (3-4), the amide linkage is hydrolyzed and citraconic acid is released, revealing the original amine.
