Thiosultap-monosodium is commercially produced by reacting 2-dimethylamino-1,3-propanedithiol with thiosulphuric acid or its sodium salt under aqueous conditions to form the monosodium salt of the thiosulphuric acid ester. This synthesis involves a nucleophilic substitution where the thiol groups of the propanedithiol intermediate bond with the thiosulphuric acid moiety.
Stomach poison with some contact and systemic action. It is a nereistoxin analogue, meaning it disrupts nerve function in insects, leading to paralysis and death
