Isethionic acid sodium
Based on 1 Customer Validation
Isethionic acid sodium salt (2-Hydroxyethanesulfonic acid sodium; Sodium isethionate) is an endogenous mammalian Taurine (HY-B0351) metabolite. Isethionic acid sodium salt forms covalent ester linkages with cholic acid. It acts as a larval settlement inhibitor for Balanus amphitrite with larval toxicity. Isethionic acid sodium salt enables the low-temperature synthesis of highly hygroscopic water-soluble sulfonates, and its acylated derivatives serve as acidic wetting solubilizers. It is used in studies related to hepatic bile acid metabolism, biological control and organic synthesis.

Biological Activity
Isethionic acid sodium salt inhibits the attachment of Balanus amphitrite cyprids in a concentration-dependent manner in an in vitro seawater bioassay system, and larval mortality increases at concentrations above 0.01 mg/mL[1].
Isethionic acid sodium salt can undergo an enzymatic reaction with bile acids under the catalysis of rat liver microsomal preparations to form choyl-ethanesulfonic acid through ester bonds[3].
