Cystine disodium by Research Lab Fine Chem Industries is a high grade reagent. This compound is derived from cystine, which is the oxidized dimer form of the amino acid cysteine. This reagent is available as a white powder which is soluble in water. Cystine is obtained from the oxidation of two cysteine molecules, by the formation of a disulfide bond. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. CAS No.: 64704-23-0 Quantity Provided: 25 gm per bottle Molecular formula: C6H10N2Na2O4S2 molecular weight: 284.30 Assay: 98 %Cystine disodium has a variety of applications in chemical and biological sectors. This compound finds several applications in the synthesis of various organic derivatives. Cystine acts as a substrate for the cystine-glutamate antiporter, the transport system of which, increases the concentration of cystine inside the cell. Cysteine supplements are often marketed as anti-aging products for the claimed purpose of improving skin elasticity. This reagent is suitable for industrial synthesis of products and research applications.
