title: Thin-layer chromatography of thiosulfonate anions.
abstract: Organic thiosulfonates of the form RS(O2)S- can be separated from the characteristic contaminants in synthetic preparations by thin-layer chromatography on silica gel. Thiosulfonates and sulfinates can both be visualized, and differentiated, by treatment of plates with a FeCl3 reagent in acetone. Data are presented for seven aromatic and six aliphatic thiosulfonate anions and the corresponding sulfonates and sulfinates. With exception of the series related to cysteic acid, Rf values are always in the order RS(O)2S- greater than RSO3- greater than RSO2-.
