Description

Dibenzoyl-L-Tartaric Acid is a high-purity chiral resolving agent and synthetic intermediate derived from L-tartaric acid. Its primary commercial value lies in its ability to separate enantiomers of chiral amines and other basic compounds, a critical process in pharmaceutical and fine chemical manufacturing. This product is essential for R&D laboratories, pharmaceutical companies, and producers of advanced intermediates requiring high stereochemical purity.

Application

• Chiral Resolution: As a resolving agent for the separation of racemic mixtures of pharmaceutical intermediates and active ingredients.
• Pharmaceutical Synthesis: Key chiral building block and auxiliary in the asymmetric synthesis of complex drug molecules.
• Catalyst and Ligand Preparation: Used in the synthesis of chiral catalysts and ligands for asymmetric catalysis.
• Analytical Chemistry: Serves as a chiral selector or derivatizing agent in chromatographic methods like HPLC for enantiomeric purity analysis.
• Fine Chemical Production: Intermediate in the manufacture of specialty chemicals requiring defined stereochemistry.
• Food & Flavor Industry: Potential use in the synthesis of chiral flavor compounds and additives, subject to appropriate grade availability.

Quality Control

Our Dibenzoyl-L-Tartaric Acid is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for demanding applications like chiral resolution and pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and performance.
