Product Name:Disodium methanedisulfonate
English Name:Disodium methanedisulfonate
CAS No.:5799-70-2
Aliases:Methanedisulfonic acid disodium salt, Methylenedisulfonic acid disodium salt
Molecular Formula:CH2(SO3Na)2
Physical Properties:White crystalline powder, freely soluble in water, slightly soluble in ethanol, insoluble in ether, benzene and other organic solvents. Its aqueous solution is nearly neutral. Melting point above 300 °C with decomposition.
Uses:Used as an additive in electroplating processes such as hard chromium plating, copper plating, and tin plating. It can increase current efficiency by about 27%, reduce corrosion of lead anodes, and improve the brightness, hardness, and adhesion of the coating. It is also used as an intermediate in organic synthesis.
Technical Specifications:
Purity: ≥99%
Appearance: white crystalline powder
Solubility: freely soluble in water, slightly soluble in ethanol
Molecular weight: 220.15
Grade: electroplating grade
