Import 2, 5-Dimercapto-1, 3, 4-Thiodiazole Dmtd — Buy in Bulk from Supplier in China

Hangzhou Bais Chemical Technology Co., Ltd supplies 2,5-dimercapto-1,3,4-thiadiazole, commonly abbreviated as DMTD, under the Petrolem® brand with product code E1310. The compound carries CAS number 1072-71-5 and is offered at a main content purity of 98%, making it suitable for use as a multifunctional additive in lubricant formulations and metalworking fluids. DMTD is a sulfur-nitrogen heterocyclic compound whose dual thiol groups provide active sites for metal surface interaction, delivering extreme pressure and anti-wear performance at relatively low treat rates.

In lubricant and metalworking fluid applications, DMTD functions as an extreme pressure additive, an anti-wear agent, and a metal deactivator, reducing copper corrosion and oxidative degradation in finished oils. Its low cost relative to other sulfurised additives makes it an economical choice for formulators blending industrial gear oils, hydraulic fluids, and cutting oils. Beyond lubricants, DMTD also serves as an intermediate in pharmaceutical synthesis, where the thiadiazole ring is a building block for certain drug molecules and corrosion inhibitor compounds.

Buyers typically include lubricant blenders, metalworking fluid manufacturers, and chemical distributors sourcing bulk quantities for reformulation or resale. Hangzhou Bais Chemical Technology is based in Yuhang District, Hangzhou, Zhejiang Province, and the listing indicates the product is available for export. Specific MOQ, pricing tiers, and packaging formats should be confirmed directly with the supplier, as these details are not specified in the listing.
