L-TARTARIC ACID 99.5% A.C.S. REAGENT (99% EE/GLC) (C005B-083584)

Application

L-(+)-Tartaric acid may be used in the synthesis of (R,R)-1,2-diammoniumcyclohexane mono-(+)-tartrate, an intermediate to prepare an enantioselective epoxidation catalyst. It may also be used as a starting material in the multi-step synthesis of 1,4-di-O-benzyl-L-threitol. It can be used a chiral resolving agent for the resolution of 2,2′-bispyrrolidine.

Chiral building block for natural products. Also forms a Diels-Alder catalyst with TiCl₂(O-i-Pr)₂.
