Chemical Structure
Basic Info
1,3-Dimercaptopropane (CAS 109-80-8) is an important organic sulfur compound with two thiol groups (-SH) in its molecular structure. At room temperature, it is a liquid that ranges from colorless to yellowish. It has a distinctive smell. It is used primarily as a pharmaceutical intermediary, a polymer cross-linking agent and a metalchelating agent. It is used in a variety of ways, including rubber vulcanization and pesticide synthesis.
It has active chemical properties, and it can form stable complexes of a variety metal ions. It is also an effective reducing agent for organic synthesis. In pharmaceutical research and development and industry, its high-purity (>=98%) product is used to synthesize anticancer drugs and counterdotes. It is a key raw material in the field fine chemicals.

Organic Synthesis
The field of chemical intermediate synthesis provides a preparation method for synthesizing 2-mercaptobenzoxazole (thiazole) compounds based on 1,3-dimercaptopropane as a thiol source. Under the protection of inert gas, in dimethyl sulfoxide solvent, substituted benzoxazole (thiazole) and 1,3-dimercaptopropane are heated and stirred at 120-140degC in the presence of a base. After 12-24 hours of reaction, the liquid is cooled down to room temperature. Then it is acidified in order to get the final product. This preparation method is characterized by its simplicity, compatibility of functional groups and high yield. The prepared 2-mercaptobenzoxazole and 2-mercaptobenzothiazole compounds are important organic synthesis intermediates, which are widely used in chemical raw materials, pesticides, medicines and other fields, and have strong practical value and social and economic benefits.
Electrochemistry
The electrochemical field provides an electroplating CoNi alloy electroplating solution additive, the additive includes chlorobenzaldehyde, 1,3-Dimercaptopropane, sodium butynol ether propane sulfonate, sodium diethylenetriamine pentaacetate, the additive can effectively inhibit abnormal deposition of CoNi, the coating has small grains, smooth surface, low internal stress, strong deep plating ability, and the electroplating effect is better than that of similar plating solutions.
Cleaning Instruments
Mix ethylene glycol, diethylene glycol monoethyl ether, dibutyloxyethyl phthalate, 1,3-Dimercaptopropane, ethanol, and propylene glycol monomethyl ether, stir to obtain a mixture A; then mix coconut oil glycol amide, glycerol monocaprylate, oleoyl sarcosine octadecylamine, 2-methylpropane sulfonic acid, sodium diisooctyl sulfonate, sodium metasilicate, and dihydroxymethylpropionic acid, stir to obtain a mixture B; heat the mixture A, add the mixture B under stirring conditions, continue stirring, and cool to room temperature to obtain an experimental glass instrument cleaning agent. The cleaning agent has a non-corrosive nature, excellent cleaning effects and a high degreasing capacity.
Separation of the sexes and detection
By step-by-step synthesis, a bifunctional polyarylether containing allyl groups and tertiary amino acids is produced. The tertiary amino acid group is then quaternized to introduce a dicationic chain and obtain a compound with both allyl side chains and dicationic. Then 1,3-Dimercaptopropane is added as a cross-linking agent, and a cross-linked anion exchange membrane with high oxidation stability and high ion conductivity is obtained by cross-linking through an efficient ene-thiol click reaction. This anion exchange membrane has higher mechanical strength, oxidation resistance and vanadium ion permeability compared to the uncross-linked one. It also exhibits a lower vanadium Ion Permeability.
