Description

(1R,2R)-(+)-1,2-Bis(4-Nitrophenyl)Ethylenediaminedihydrochloride, Min. 98% is a high-purity chiral diamine derivative, serving as a critical building block and chiral ligand in advanced organic synthesis. Its value lies in its ability to impart stereoselectivity in catalytic reactions and act as a precursor for complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require enantiomerically pure intermediates for the development of active ingredients and functional materials.

Application

• Chiral Ligand in Asymmetric Catalysis: Employed in metal-catalyzed reactions such as hydrogenation, epoxidation, and Diels-Alder reactions to achieve high enantiomeric excess.
• Pharmaceutical Intermediate: A key precursor in the synthesis of enantiomerically pure drug candidates, particularly those targeting neurological and cardiovascular diseases.
• Agrochemical Synthesis: Used in the development of chiral pesticides and herbicides where specific stereochemistry is crucial for biological activity and environmental safety.
• Resolution Agent: Functions as a chiral selector for the separation of racemic mixtures via diastereomeric salt formation.
• Material Science Research: A monomer or building block for creating chiral polymers, metal-organic frameworks (MOFs), and other functional materials with specific optical properties.
• Analytical Chemistry: Serves as a standard or reagent in chiral chromatography and spectroscopy for method development and validation.

Quality Control

Every batch of our (1R,2R)-(+)-1,2-Bis(4-Nitrophenyl)Ethylenediaminedihydrochloride is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for high-purity chiral chemicals. Comprehensive testing includes chiral purity (enantiomeric excess), chemical purity (HPLC), and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided with each shipment and are available upon request.

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 (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions to prevent degradation. For long-term storage, consider using a desiccant.
