Yantai Heng Nuo Chemical Technology Co., Ltd offers 2, 5-dimercapto-1, 3, 4-thiadiazole (DMTD), a white to light yellow powder with a molecular weight of 150 g/mol and a melting point of 158-163°C. The product has a purity exceeding 99% and a fineness where over 99% passes through a 320-mesh sieve. Its CAS number is 1072-71-5, and the EINECS number is 214-014-1.
DMTD is a versatile sulfur-nitrogen heterocyclic compound. Its structure, featuring two thiol groups, makes it an effective metal deactivator and antioxidant in lubricating oils, particularly for inhibiting copper corrosion. The S-N bond also imparts extreme pressure and anti-wear properties when incorporated into polymer macromolecules. Derivatives of DMTD find use as curing agents for halogenated rubber and have applications in pharmaceutical synthesis.
Industrial buyers include lubricant additive manufacturers, rubber product companies, and electrochemical researchers. The material is also investigated for use as a battery anode material and a color reagent for non-ferrous metals. Sourcing from Yantai Heng Nuo requires confirming the exact lot specifications, packaging (typically in drums), and the supplier's capacity for consistent batch production from their Yantai, Shandong facility.

Before ordering 2, 5-dimercapto-1, 3, 4-thiadiazole from Yantai Heng Nuo, request a current batch Certificate of Analysis to verify the purity, melting point, and moisture content against your application requirements. Clarify the minimum order quantity and whether the product is manufactured in-house or sourced.
For logistics, confirm the packaging format and net weight. Discuss suitable Incoterms for shipment from Yantai port. Given the product's moisture sensitivity, ensure the packaging is robust for sea freight and consider the lead time from order to shipment, which should be specified by the supplier.
Upon receipt, conduct incoming quality control. A simple melting point test can quickly screen for gross deviations. For critical applications, a full assay (HPLC or titration) is recommended. Store the material according to the supplier's guidelines to maintain its stability and performance characteristics.
