Description

(-)-Dibutyl-D-Tartrate is a high-purity chiral ester derived from D-(-)-tartaric acid. This compound serves as a versatile chiral auxiliary and resolving agent, critical for the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise stereochemical control in asymmetric synthesis and chiral separations.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, amino acids, and other basic compounds.
• As a chiral ligand or catalyst component in asymmetric synthesis reactions, including hydrogenations and oxidations.
• As a key chiral intermediate in the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• In the preparation of liquid crystals and advanced organic materials where chirality influences physical properties.
• For use in analytical chemistry as a chiral selector in chromatography (e.g., chiral stationary phases).
• In agrochemical research for the development of enantiomerically pure pesticides and herbicides.
