  • Applications

    Diethyl L-tartrate, CAS 87-91-2, is an essential chiral building block in organic chemistry, widely employed as the ligand component in Sharpless asymmetric epoxidation to impart high stereoselectivity, serving as an intermediate in the synthesis of pharmaceuticals (macrolide antibiotics, cholesterol-lowering statins, antiviral agents), agrochemicals, flavors and fragrances; it is also used as a resolving agent through selective salt or ester formation, a modifier of biodegradable polymer surfaces, an additive in chromatographic analyses, and a mild acidulant in specialized food formulations.
