  • Title: 5-(2-Aminoethyl)dithio-2-nitrobenzoate as a more base-stable alternative to Ellman's reagent.
    Author: Zhu J, Dhimitruka I, Pei D.
    Journal: Org Lett; 2004 Oct 14; 6(21):3809-12. PubMed ID: 15469355.
    Abstract:
    [reaction: see text] 5-(2-Aminoethyl)dithio-2-nitrobenzoate (ADNB) reacts with free thiols with kinetics similar to those of Ellman's reagent but has dramatically improved stability under alkaline conditions, making it an excellent alternative to Ellman's reagent for the quantitation of thiol contents and enzymatic assays under basic pH conditions.
