Description

Ester L-Dibenzoyl Tartaric Acid Salt is a high-purity chiral resolving agent and synthetic intermediate. This compound is critical 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 advanced materials sectors for asymmetric synthesis and analytical method development.

Application

• Chiral Resolution Agent: For the separation of racemic mixtures, particularly of amines and other basic pharmaceuticals.
• Pharmaceutical Intermediate: Used in the asymmetric synthesis of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity.
• Catalyst and Ligand Precursor: In the development of chiral catalysts for stereoselective reactions.
• Analytical Chemistry Standard: As a reference standard for HPLC and other chromatographic methods to determine enantiomeric excess.
• Agrochemical Synthesis: In the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: For manufacturing specialty chemicals where specific chirality dictates function and performance.

Quality Control

Our Ester L-Dibenzoyl Tartaric Acid Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and fine chemical applications. A comprehensive Certificate of Analysis (COA), detailing purity, chiral purity, and impurity profiles, is provided with every shipment to guarantee consistent quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
