In the intricate world of pharmaceutical and fine chemical manufacturing, achieving high enantiomeric purity is not just desirable—it's often a regulatory and efficacy requirement. Chiral compounds, molecules that exist as non-superimposable mirror images (enantiomers), can exhibit dramatically different biological activities. This is where the role of chiral resolving agents becomes paramount. Among the most effective and widely utilized is Di-p-anisoyl-D-tartaric Acid (CAS 191605-10-4).

As a premier supplier and manufacturer of specialty chemicals, we understand the critical need for reliable and high-quality intermediates. Di-p-anisoyl-D-tartaric Acid, with its specific optical rotation and robust chemical structure, stands out as an indispensable tool for chemists worldwide. This article explores why this compound is so vital and how purchasing it from a trusted source like NINGBO INNO PHARMCHEM CO.,LTD. can significantly benefit your operations.

What is Di-p-anisoyl-D-tartaric Acid?

Di-p-anisoyl-D-tartaric Acid (CAS 191605-10-4) is a derivative of D-tartaric acid, a naturally occurring organic acid. It is characterized by the presence of two p-anisoyl groups esterified onto the hydroxyl groups of the tartaric acid backbone. This specific structure imparts excellent chiral properties, making it an exceptional agent for resolving racemic mixtures.

Key Properties of Di-p-anisoyl-D-tartaric Acid include:

  • Appearance: White to off-white crystalline powder.
  • Purity: Typically ≥99.0% (HPLC).
  • Optical Rotation: A specific range, often +165° to +171° (c=1, EtOH), indicating its high enantiomeric purity.
  • Molecular Formula: C20H18O10
  • Molecular Weight: 418.35 g/mol

The Crucial Role in Chiral Resolution

Chiral resolution is the process of separating a racemic mixture—an equimolar mixture of two enantiomers—into its individual enantiomers. Di-p-anisoyl-D-tartaric Acid excels in this area by forming diastereomeric salts or complexes with the target racemic compounds. These diastereomers have different physical properties, such as solubility, which allows for their separation through techniques like fractional crystallization or chromatography. For many pharmaceutical companies, successfully isolating a specific enantiomer is crucial, as one enantiomer may be therapeutically active while the other is inactive or even harmful.

For researchers and procurement managers looking to buy Di-p-anisoyl-D-tartaric acid for chiral resolution, sourcing from a reliable supplier in China like NINGBO INNO PHARMCHEM CO.,LTD. ensures consistent quality and batch-to-batch reproducibility, which is vital for scaling up processes.

Applications in Asymmetric Synthesis

Beyond resolution, Di-p-anisoyl-D-tartaric Acid also serves as a valuable chiral auxiliary or catalyst in asymmetric synthesis. In asymmetric synthesis, the goal is to create chiral molecules with a preference for one enantiomer over the other from achiral or prochiral starting materials. By incorporating Di-p-anisoyl-D-tartaric Acid into the reaction system, chemists can influence the stereochemical outcome of the reaction, leading to the formation of a desired enantiomer with high selectivity.

The demand for enantiomerically pure intermediates in the synthesis of Active Pharmaceutical Ingredients (APIs) is immense. Purchasing high purity Di-p-anisoyl-D-tartaric acid as an asymmetric synthesis intermediate from a reputable manufacturer is a strategic move for companies aiming for efficiency and product integrity. We offer competitive pricing for this essential chemical, making it accessible for both R&D and large-scale production.
