Application

Aminomethanesulfonic acid can be used as a reactant to synthesize: 1-Sulfomethyltetrazole-5-thiol disodium salts, which are useful key intermediates for the preparation of cefonicid sodium. Tridentate N-(2-hydroxybenzyl)aminomethane sulfonic acid Schiff-base ligand by reacting with salicylaldehyde.
It can also be used to functionalize the surface of single-walled carbon nanotubes (SWCNT) or porous metal-organic frameworks (MOF) to introduce the sulfonic acid functional groups for the preparation of nanocomposites.

It is well known that taurine stimulates ATP-dependent calcium ion uptake at low calcium ion concentrations. However, aminomethanesulfonic acid, the lower homologue of taurine, inhibits calcium ion uptake under the same experimental conditions. The higher homologue of taurine, 3-aminopropanesulfonic acid
