Determination of thiols with o-iodosobenzoate
Abstract
Thiol groups are titrated directly with o-iodosobenzoate reagent at pH 7 employing leuco-2, 6-dichlorophenolindophenol with potassium iodide as indicator. This modification avoids errors that result from side-reactions of iodine, which take place if the excess of iodosobenzoate is made to react with acidified potassium iodide.
