Sodium Taurocholate Hydrate is the sodium salt of taurocholic acid, a primary bile acid conjugated with taurine, existing as a crystalline hydrate. It is a high-purity bile salt widely used as a biochemical surfactant and solubilizing agent in pharmaceutical and life science research. The product is typically manufactured through chemical synthesis or semi-synthesis from cholic acid, followed by conjugation with taurine and subsequent salt formation, yielding a stable hydrate form.
In the pharmaceutical and biotech industries, Sodium Taurocholate Hydrate serves as a critical excipient for enhancing the solubility and bioavailability of poorly water-soluble drugs, particularly in oral and injectable formulations. It is also a key component in cell culture media, where it facilitates lipid digestion and absorption, and finds use in membrane protein research as a mild detergent for solubilization and reconstitution. Its ability to form mixed micelles makes it indispensable in studies of bile acid metabolism, cholestasis, and drug transport mechanisms.
