Sodium Azide → HCID 178527658, compound

Participants

Reaction Steps

A mixture of 45.3 g. (0.19 mol) of methyl sulfomethyldithiocarbamate potassium salt and 16.9 g. (0.26 mol) of sodium azide in 425 ml. of water was heated at 80° C. for 4.75 hours. The reaction mixture was passed through an Amberlite IR-120H ion exchange resin column and eluted with water until the pH of the eluant became 3.5. The eluant was extracted with ether and the aqueous solution was evaporated to dryness to give 1-sulfomethyltetrazole-5-thiol. The disodium salt is prepared using sodium methoxide-methanol in isopropanol. 1-Sulfomethyltetrazole-5-thiol sodium salt was precipiated and was collected by filtration.
