(-)-Dimethyl 2,3-O-isopropylidene-L-tartrate（Cat No.:R060831）is a chiral organic compound derived from L-tartaric acid. It features two methyl ester groups and a 2,3-O-isopropylidene protecting group that forms a cyclic acetal across the hydroxyl groups. This compound is widely used as a chiral building block and auxiliary in asymmetric synthesis, particularly in the preparation of enantiomerically pure compounds. Its rigid, stereodefined structure aids in inducing chirality in various organic transformations. It is also used in the synthesis of pharmaceuticals, natural products, and fine chemicals, where stereocontrol is critical for biological activity.
