Basic Info
It is a fine chemical compound that can be used in the pharmaceutical and chemical fields as a carbonyl protectant, as well as in biochemistry as a metal-complexing agent. The production and preparation of this product is a bit difficult. Its production and preparation process is somewhat difficult. The traditional method is to react thiourea directly with 1,2-dibromoethane with a 90% yield. Next, use 8-10 times the strong base of KOH from the cracked raw material and heat and reflux it for 5 hours. Add 50% sulfuric under nitrogen dropwise to neutralize. Add until the reactant becomes acidic on Congo red test papers. Finally, add excess 20% sulfuric. Collect the distillate using steam distillation. Separate the oil The actual process is difficult to control and has a low yield of 30 to 40%. It also requires complex equipment and a long operation. The process hasn’t been improved in decades. The product is largely imported due to its high production costs.

1. Intermediates for pharmaceuticals
In pharmaceutical synthesis, 1,2-ethanedithiol can be used to protect carbonyl groups. It is also used in the preparations of antiviral and antibiotic drugs. Its molecule contains two thiol (-SH) groups that can form a thioketone with the carbonyl, protecting it from destruction in complex reactions. This improves the efficiency of synthesis.
2. Food flavors
It is a strong odor. However, 1,2-ethanedithiol can be used to flavor food at very low concentrations.
3. Metal chelating agent
In industrial and biochemical applications, 1,2-ethanedithiol is used as a metal-ion chelating agents. It can form stable complexes, such as those with copper, mercury and lead.
4. Synthesis of peptide resins and organic synthesis
This compound is used for organic reactions like Claisen condensation or Michael addition. This compound is used as a cleavage component in the synthesis of solid phase peptides (in combination with trifluoroacetic acids), and can be used to improve the purity of the crude peptides, or the conversion rate of the oxidized ones.
5. Materials Science (Preparation of Antimony oxide film)
As a solvent, 1,2-ethanedithiol mixed with ethylenediamine can be used to make antimony oxide film by electrodeposition. It is used to make optoelectronic material and offers high yield and a short reaction time.
6. Modification of Cable Sheath
As an additive 1,2-ethanedithiol improves the mechanical properties of PMA EEA cable sheaths. It also increases corrosion resistance and compressive strengths.
7. Agriculture (slow release fertilizer coating).
This compound is used in rice fertilizers to regulate the release of nutrients, increase fertilizer efficiency, and promote crop growth.
