Description

(-)-Di-tert-Butyl D-Tartrate is a high-purity chiral auxiliary and building block derived from natural D-tartaric acid. This compound is valued for its role in asymmetric synthesis, where it serves as a key ligand and resolving agent to induce enantioselectivity in critical chemical transformations. It is essential for research and production in the pharmaceutical, agrochemical, and fine chemical industries, enabling the creation of single-enantiomer active ingredients.

Application

• As a chiral ligand in asymmetric catalysis, including hydrogenation and oxidation reactions.
• As a resolving agent for the separation of racemic mixtures of amines, acids, and alcohols.
• As a key synthetic intermediate in the production of enantiomerically pure pharmaceuticals.
• In the synthesis of specialty chemicals and advanced materials requiring precise stereochemistry.
• For research and development in academic and industrial organic chemistry laboratories.
• In the preparation of chiral stationary phases for analytical chromatography.
