Aminomethylsulfonic acid (also called aminomethylenesulfonic acid and aminomethanesulfonic acid) is an organic chemical compound, with amino (–NH
2) and sulfonic acid (–SO
2–OH) groups on the carbon atom. Its chemical formula is NH
2CH
2SO
2OH, and it has a molar mass of 111.12 g/mol.
Synthesis
Aminomethane sulfonic acid can be made by the reaction between hexamethylenetetramine (hexamine) with sulfur dioxide (SO2) in an aqueous environment.[2]
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.[3] Its density is ~1.7 g/cm3.[4]
Aminomethanesulfonic acid appears as a white crystalline solid that dissolves readily in water. It exhibits amphoteric behavior, meaning it can act as either an acid or a base depending on the conditions. Heating the compound above 280 °C leads to decomposition, releasing sulfur dioxide and other gaseous products.[5]
Uses
Although aminomethanesulfonic acid has limited commercial use, it has been employed in research as a reagent and as a buffering agent. It has also been studied as a structural analog of taurine in biochemical research, helping to investigate metabolic pathways and sulfonic acid derivatives.[6]
Dangers
Aminomethanesulfonic acid can cause skin and eye burns, it is an dermatotoxin.
