L-Cystine FCC is a non-essential amino acid vital for human development formed by the dimerization of two cysteines. L-Cystine is used as an antioxidant, protecting tissues against radiation and pollution. It finds application in protein synthesis. It is required for utilization of vitamin B6 and is useful in healing burns and wounds. L-Cystine FCC is found in various nutritional products, acne treatments, and creams to treat cervical injury or inflammation. Its derivatives act as ligands for neuronal nicotine receptors and have various pharmacological activities. It serves as a building block for proteins and is crucial for maintaining a healthy immune system.

FCC Grade: Chemicals that are FCC grade meet standards outlined in the Food Chemicals Codex. The FCC was acquired by the USP, but still uses the Codex for food chemical standards.

Copper oxide flotation activator TMTN-2 (sodium thiadiazole salt) Cas; 55906-42-8
Composition: Trimercaptotriazine sodium salt, thiadiazole sodium salt and other active groups
Technical Indicator Characters: Light yellow liquid proportion: 1.10-1.30 (30 ~C) Low temperature stability: -20 ~C pH value: 7.0-8.5
Introduction: Dimercapto-1,3,4-thiadiazole (DMTD), trimercapto-triazine (TMT) sodium salts have thiadiazole in their molecular structure. Triazine heterocycles also have highly acidic thiol groups. Thiadiazole and sodium triazine salts form conjugation effects with thiadiazole heterocycles. Therefore, thiadiazole and sodium triazine salts have certain charge attraction to some copper-bearing gold ores and can be used as flotation reagents for copper ores. Azole and triazine salts have obvious activation effect on the flotation of copper oxide minerals. A new flotation reagent TMTN-2 was prepared by flotation of copper oxide ore with DMTD alkali metal salt as activator and xanthate as collector. On this basis, a lot of popularization and application work has been carried out, and the flotation agent TMTN-2 for copper oxide ore has been produced in batches for use in mines. DMTD salts and triazine salts have been successfully used in the flotation production of copper oxide ores, so that the concentrator can obtain better benefits.

English name: 2,5-Di (t-nonyldithio) - 1,3,4-thiadiazole;
Foreign business names: Amoco 158; Mobilad C 610
Product Description: This product is an upgraded substitute of T56 1, a traditional thiadiazole derivative. The sulfur content can reach more than 31%. The metal deactivator TH571 is a yellow-brown transparent liquid made from thiadiazole and long molecular chain mercaptan by introducing S and N heteroatoms with anti-wear activity into the main chain of macromolecule and through complex oxidative coupling reaction. The product has excellent oil solubility, Metal Deactivation characteristics, extreme pressure and wear resistance, oxygen resistance, corrosion resistance and the ability to reduce metal activity. Compared with the traditional thiadiazole derivative T561, the modified thiadiazole derivative TH571 has better oil solubility and can form a complete protective film on the surface of copper. The protective film has better corrosion inhibition effect on copper. It is widely used as metal deactivator in automobile engine oil, gear oil and metal cutting fluid, extreme pressure antiwear agent in lubricating oil, and can significantly inhibit the corrosion of copper. The corrosiveness of sulphide produced in lubricating oil during use is an excellent antioxidant. It is used as bearing preservative, antiwear agent and metal deactivator in antiwear hydraulic oil, cryogenic hydraulic oil, steam turbine oil and gasoline engine oil.
It is used as extreme pressure agent, bacteria and oxidation inhibitor in emulsifier, and as antioxidant in internal combustion engine oil. It is characterized by low dosage and high performance. It is used in oil products to form a protective film by interacting with non-ferrous metal surface. It can effectively prevent the corrosion of metal caused by active sulfur and acidic substances produced by oxidation in additives. At the same time, it also inhibits the catalytic oxidation of metals and metal ions on oil products and makes them lose active particles.
