Description

(1R,2R)-1,2-Bis(2-Methoxyphenyl)Ethane-1,2-Diamine, Min. 97% is a high-purity chiral diamine building block of significant importance in asymmetric synthesis. This compound matters because its rigid, C2-symmetric structure makes it an excellent ligand or catalyst precursor for creating enantiomerically pure products, which are critical in advanced pharmaceutical development. It is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for applications requiring high stereoselectivity.

Application

• Chiral Ligand in Asymmetric Catalysis: Used in the synthesis of metal complexes for enantioselective hydrogenation, alkylation, and other C-C bond-forming reactions.
• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of active pharmaceutical ingredients (APIs) with specific stereochemistry, particularly in neurology and oncology.
• Agrochemical Synthesis: Employed in the development of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Integral to the manufacture of specialty chemicals, flavors, and fragrances where optical purity is paramount.
• Academic & Industrial Research: A valuable tool for method development and exploring new asymmetric synthetic pathways in R&D laboratories.
• Polymer Modification: Can be used to introduce chiral centers into polymer backbones for advanced materials with specific optical or mechanical properties.

Quality Control

Our (1R,2R)-1,2-Bis(2-Methoxyphenyl)Ethane-1,2-Diamine is produced under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes rigorous analytical testing, including chiral HPLC to confirm enantiomeric excess and identity verification. Certificates of Analysis (COA) detailing purity, chiral purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption.
