Administrative data
Description of key information
Magnesium dihydrogen disulfite (Mg(HSO3)2, molecular weight 186.45 g/mol), CAS No.13774-25-9, EC No.237-403-8
Appearance: inorganic, clear aqueous solution.
Solubility in water: very soluble; ca. 30 % w/wCorrosive to metals: GHS criteria not met (weight loss ≤ 13.5 %)
Waivers are proposed for most of the endpoints: melting and boiling point, density, particle size distribution, vapour pressure, partition coefficient, surface tension, flash point, auto flammability, flammability, explosiveness, oxidising properties, stability in organic solvents, dissociation constant and viscosity, as well as for pyrophoric properties and flammability in contact with water.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
