Thiosulfinate, also known as thiosulfinic acid, is a member of the class of compounds known as thiosulfinic acid esters. Thiosulfinic acid esters are organic compounds containing an ester of thiosulfinic acid with the general structure RS(=S)OR' (R, R'=alkyl, aryl). Thiosulfinate is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Thiosulfinate can be found in a number of food items such as salmonberry, nuts, summer grape, and red bell pepper, which makes thiosulfinate a potential biomarker for the consumption of these food products. In organosulfur chemistry, thiosulfinate is a functional group consisting of the linkage R-S(O)-S-R (R are organic substituents). Thiolsulfinates are also named as alkanethiosulfinic (or arenethiosulfinic) acid esters. They are the first member of a family of compounds containing an oxidized disulfide bond. Other members of this family include thiosulfonates (R-SO2-S-R), α-disulfoxides (R-S(O)-S(O)-R), sulfinyl sulfones (R-S(O)-SO2-R), and α-disulfones (R-SO2-SO2-R), all of which are known. The thiosulfinate group can occur in cyclic as well as acyclic structures .
