Product Description

Product Description

Basic Information

  • Product Name: 2,5-Dimercapto-1,3,4-thiadiazole (DMTD)
  • Chemical FormulaC2H4N2S3
  • Molar Mass: 152.26 g/mol
  • CAS Number: 1072-71-5
  • Appearance: Typically a white to light yellow crystalline powder
  • Odor: Characteristic mercaptan-like smell
  • Solubility: Slightly soluble in water; readily soluble in organic solvents such as ethanol, acetone, and dimethyl sulfoxide (DMSO)

Chemical Properties
  1. Reactivity of Mercapto Groups
    • The two mercapto (-SH) groups exhibit strong nucleophilicity, readily forming stable coordination compounds with metal ions (e.g., Cu², Fe³, Zn²), demonstrating excellent metal chelating ability.
    • Prone to oxidation, forming disulfides (e.g., bis(2,5-dimercapto-1,3,4-thiadiazole)) in air or under oxidizing conditions.
  2. Heterocyclic Stability
    • The thiadiazole ring (a five-membered heterocycle containing N and S atoms) shows moderate chemical stability, resistant to high temperatures and acid-base environments, making it suitable for applications in harsh conditions.
  3. Complexing Ability
    • Binds to metal surfaces through mercapto groups and heterocyclic nitrogen atoms, forming a dense protective film to inhibit corrosion.

Applications
  1. Metal Corrosion Inhibitor
    • Widely used in petrochemical, electroplating, and water treatment industries, providing significant corrosion protection for metals like copper, iron, and aluminum. Examples include:
      • As an additive in lubricants to prevent corrosion of metal components;
      • In acidic media (e.g., hydrochloric acid, sulfuric acid) for corrosion inhibition during metal pickling.
  2. Polymer Additive
    • Acts as an antioxidant and vulcanization accelerator in rubber and plastics, enhancing material resistance to aging and mechanical strength.
    • Used as a stabilizer in polyurethanes and epoxy resins to inhibit thermo-oxidative degradation.
  3. Pharmaceuticals and Biology
    • Some derivatives exhibit antibacterial and antiviral activities, serving as intermediates in pharmaceutical synthesis.
    • The chelating ability of mercapto groups is studied for heavy metal detoxification (e.g., mercury, lead poisoning).
  4. Electroplating and Surface Treatment
    • Addition of DMTD to electroplating baths improves coating uniformity and adhesion, reducing pinholes and cracks.

Safety and Precautions
  • Toxicity:
    • Mercapto groups are irritating; inhalation or skin contact may cause allergic reactions. The oral LD50 for rats is approximately 800 mg/kg (low toxicity).
  • Protection:
    • Wear gloves and masks during handling to avoid direct contact with skin and mucous membranes;
    • Store in a cool, dry place away from oxidizers and strong acids.
  • Environmental Impact:
    • High sulfur content requires proper wastewater treatment to prevent harm to aquatic life.
