CAS 25985-57-3: 2-[(Aminoiminomethyl)thio]ethanesulfonic acid

2-(2-Sulfoethyl)pseudourea is a substance that is found in the body as an intermediate product of the urea cycle. It is also used as a protective agent for beet sugar and other food products. 2-(2-Sulfoethyl)pseudourea has been shown to be effective against malonic acid, tricine, and arginine. The reaction with malonic acid yields 2-sulfoethylmalonic acid, which can then be oxidized by tricine to yield 2-sulfoethylglyoxal. This substance also reacts with arginine to produce 2-sulfoethylaminoadipic semialdehyde.
