Application
Molosultap (belonging to the class of salinomycin pesticides) is a broad-spectrum, highly effective, low-toxicity, and low-residue biomimetic pesticide.
Chemical Properties
Pure product is white crystal, m.p. 169～171°C (decomposition), relative density 1.30～1.35 (20°C). It is hygroscopic. Freely soluble in water, slightly soluble in methanol, dimethylformamide, dimethyl sulfoxide, insoluble in acetone, ethyl ether, chloroform, ethyl acetate and benzene. Stable in acidic and neutral solution, easily decomposed in alkaline solution. Industrial product is amorphous granular solid, m.p. 142～143℃.
Definition
ChEBI: An organic sodium salt that is the disodium salt of thiosultap. An insecticide used to control various pests on rice, vegetable, and fruit trees.
Production Methods
Thiosultap-disodium is commercially produced by reacting 2-dimethylamino-1,3-propanedithiol with disodium thiosulfate under aqueous conditions to form a stable thiosulfuric acid ester salt. This synthesis involves nucleophilic substitution where the thiol groups of the propanedithiol intermediate bond with the thiosulfate moiety, yielding the disodium salt. The reaction is typically carried out in water or methanol at controlled temperatures to prevent hydrolysis and ensure product stability.
Mechanism of action
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
Safety Profile
A poison by ingestion
and subcutaneous routes. Mutation data
reported. When heated to decomposition it
emits toxic vapors of NOx and SOx.
