Abstract
IN certain circumstances hydrogen sulphide, cysteine and related sulphydryl compounds react with 2 : 6-dichlorophenol-indophenol (indophenol) and thus may interfere with the determination of ascorbic acid using this reagent. In view of the known ability of p-chloromercuribenzoic acid to combine with sulphydryl compounds1, the possibility of using this reagent to suppress such interference has been examined.
