Properties

Aminomethanesulfonic acid is a corrosive solid. It could be thought of as the sulfonic acid analogue of glycine, just like aminomethylphosphonic acid is the phosphonic analogue of glycine. ^[2] Its density is ~1.7 g/cm³. ^[3]

Synthesis

Aminomethane sulfonic acid can be made by the reaction between hexamethylenetetramine (hexamine) with sulfur dioxide (SO₂) in an aqueous environment. ^[4]

Dangers

Aminomethanesulfonic acid can cause skin and eye burns, it is an dermatotoxin.
