Description
3,5-Dichloro-2-hydroxybenzenesulfonic acid, disodium salt is a reagent used to produce peroxides when combined with 4-aminoantipyrine.  It is also used in quantification of hydrogen peroxide through horseradish peroxidase-mediated conversion of itself and 4-aminoantipyrine to a colored product.  Under this principle, it is used to determine uric acid in serum as oxidation of uric acid in a uricase-catalyzed reaction yields hydrogen peroxide.
