Description

Dibenzoyl-D-Tartaric Acid is a high-purity chiral resolving agent and synthetic intermediate derived from natural tartaric acid. This compound is critically important for the separation of enantiomers in pharmaceutical development and fine chemical synthesis, ensuring the production of optically pure substances. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for asymmetric synthesis and chiral resolution processes.

Application

• Chiral Resolution Agent: Widely used for the separation of racemic mixtures, particularly for amines and other basic pharmaceuticals, to isolate the desired enantiomer.
• Pharmaceutical Intermediate: Serves as a key building block in the asymmetric synthesis of active pharmaceutical ingredients (APIs) requiring high stereochemical purity.
• Catalyst and Ligand Precursor: Employed in the preparation of chiral catalysts and ligands for enantioselective reactions.
• Analytical Chemistry: Used as a chiral selector or derivatizing agent in chromatographic methods like HPLC for enantiomeric purity analysis.
• Fine Chemical Synthesis: Applied in the production of specialty chemicals, flavors, and fragrances where optical activity is essential.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new chiral methodologies and compound libraries.

Quality Control

Our Dibenzoyl-D-Tartaric Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include chiral purity, assay, and identification. Certificates of Analysis (COA) detailing specific results for each batch are available upon request to support your quality assurance and regulatory compliance needs.

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 absorption of atmospheric moisture.
