Chemical Properties

Purification Methods

It crystallises from H2O as the dihydrate and decomposes at higher temperatures. Store it in a closed container in a cool place. It is insoluble in EtOH and Et2O and is a good reducing agent. [X-ray structure: Tuter J Chem Soc 3064 1955.] Note that this compound {HOCH2SO2Na} should not be confused with formaldehyde sodium bisulfite adduct {HOCH2SO3Na} from which it is prepared by reduction with Zn. [Beilstein 1 IV 3052.]
