Description

Ethylenediamine Di-L-(+)-Tartrate is a high-purity, crystalline salt formed from ethylenediamine and L-(+)-tartaric acid. This compound is a critical chiral auxiliary and resolving agent, valued for its ability to separate enantiomers in asymmetric synthesis and pharmaceutical manufacturing. It is essential for industries requiring high stereochemical purity, including advanced pharmaceutical intermediates, fine chemical synthesis, and specialized catalyst preparation.

Application

• Chiral Resolution Agent: For the separation of racemic mixtures of acids, amines, and other chiral compounds in pharmaceutical and fine chemical production.
• Asymmetric Synthesis: As a chiral building block or ligand precursor in catalytic asymmetric reactions.
• Pharmaceutical Intermediate: In the synthesis of active pharmaceutical ingredients (APIs) where specific stereochemistry is required for biological activity.
• Analytical Chemistry: Used as a standard or reagent in chromatographic methods for enantiomeric purity analysis.
• Catalyst Preparation: As a precursor for metal-complex catalysts used in stereoselective transformations.
• Biochemical Research: In studies involving enzyme inhibition, receptor binding, and other stereospecific biological processes.

Quality Control

Our Ethylenediamine Di-L-(+)-Tartrate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, chiral purity, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 product stability and handling properties.
