Applications
Reagent for determination of sufhydryl groups.5,5′-dithiobis-(2-nitrobenzoic acid) is widely utilized as a non-fluorescent probe to quantify the number or the concentration of thiol groups in a sample. It acts as a cleavable cross-linking agent. It finds an important application as a sensitive reagent for determining free sulfhydryl content in proteins, peptides, and tissues. It is also employed in high-performance liquid chromatography (HPLC) to determine the alkylthiol content.

Solubility
Soluble in water and ethanol.

Notes
Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong bases.
