Description

Bis(2-Ethylhexyl) [R(R*,R*)]-Tartrate is a high-purity chiral diester derived from L-(+)-tartaric acid, serving as a critical chiral selector and resolving agent in asymmetric synthesis. Its primary value lies in its ability to induce enantioselectivity, making it indispensable for the production of single-enantiomer compounds with high optical purity. This product is essential for R&D and manufacturing chemists in the pharmaceutical, agrochemical, and fine chemical industries who require reliable, high-performance chiral auxiliaries for complex synthetic pathways.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, acids, and alcohols.
• Key intermediate in the synthesis of pharmaceutical active ingredients (APIs) requiring specific stereochemistry.
• Utilized as a chiral ligand or additive in asymmetric catalysis to control reaction stereoselectivity.
• Component in the preparation of chiral stationary phases (CSPs) for analytical and preparative chromatography.
• Building block for advanced functional materials and liquid crystals.
• Used in agrochemical research for developing enantiomerically pure herbicides and pesticides.
• Employed in flavor and fragrance synthesis where specific stereoisomers define the organoleptic profile.
