Description

Di-p-Anisoyl-D-Tartaric Acid is a high-purity chiral resolving agent and synthetic intermediate derived from tartaric acid. This compound is critically important for its ability to separate enantiomers in pharmaceutical synthesis and fine chemical production, ensuring the purity and efficacy of single-isomer drugs. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise chiral control in their processes.

Application

• Chiral Resolution Agent: Key for the separation of racemic mixtures in pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• Asymmetric Synthesis: Used as a chiral auxiliary or catalyst in stereoselective organic synthesis.
• Pharmaceutical Intermediate: Serves as a building block for the synthesis of complex, optically active drug molecules.
• Analytical Chemistry: Employed as a chiral selector in High-Performance Liquid Chromatography (HPLC) for enantiomeric purity analysis.
• Agrochemical Synthesis: Used in the production of enantiomerically pure pesticides and herbicides.
• Fine Chemical Production: Integral to the manufacture of specialty chemicals requiring high optical purity.

Quality Control

Our Di-p-Anisoyl-D-Tartaric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for chiral synthesis and resolution. Certificates of Analysis (COA) detailing purity, optical rotation, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
