English description（英文原文，共 904 字符）
Product Name:Dipotassium methanedisulfonate
English Name:Dipotassium methanedisulfonate
CAS No.:6291-65-2
Aliases:Methanedisulfonic acid dipotassium salt, Potassium methanedisulfonate
Molecular Formula:CH4O6S2·2K
Physical Properties:White to off-white crystalline powder, readily soluble in water, with a neutral or weakly alkaline aqueous solution. Insoluble in organic solvents such as ethanol and diethyl ether. Decomposes upon heating, potentially releasing sulfur oxide gases at high temperatures.
Uses:Mainly used as an additive in chromium electroplating to improve coating uniformity and gloss. It also serves as an organic synthesis intermediate for introducing the methanedisulfonyl group.
Technical Specifications:
Assay (on dry basis) ≥ 98.0%
Solubility in water: clear and transparent, no insoluble matter
Loss on drying ≤ 1.0%
Iron content ≤ 0.005%
Heavy metals (as Pb) ≤ 0.001%
