Description

(-)-Dibenzoyl-L-Tartaric Acid Monohydrate is a high-purity chiral resolving agent and synthetic intermediate. This compound is critically important for the separation of racemic mixtures, particularly in the pharmaceutical industry, due to its ability to form diastereomeric salts with chiral amines. It is primarily needed by manufacturers in the pharmaceutical, fine chemical, and academic research sectors for the production of enantiomerically pure active pharmaceutical ingredients (APIs) and advanced intermediates.

Application

• Chiral Resolution of Racemic Amines: As a classical resolving agent for the separation of enantiomers via diastereomeric salt formation.
• Pharmaceutical Intermediate: Used in the synthesis of enantiopure drugs and bioactive molecules.
• Asymmetric Synthesis Catalyst: Employed as a chiral auxiliary or ligand in stereoselective reactions.
• Analytical Chemistry Standard: Serves as a reference standard for chiral HPLC methods and purity analysis.
• Fine Chemical Production: A key building block for complex chiral compounds in specialty chemistry.
• Academic & Process Research: Utilized in R&D for developing new chiral separation protocols and synthetic methodologies.

Quality Control

Our (-)-Dibenzoyl-L-Tartaric Acid Monohydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity and chemical assay, to ensure it meets the high standards required for chiral resolution and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific rotation is 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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect performance and purity.
