Description

Cupriethylenediamine is a coordination complex of copper with ethylenediamine, widely recognized as a key reagent in analytical chemistry and polymer science. Its primary commercial value lies in its role as the active component in the standard solvent for determining the intrinsic viscosity of cellulose, a critical parameter for quality control in the pulp and paper industry. This product is essential for R&D laboratories, chemical manufacturers, and quality assurance departments in sectors including textiles, pharmaceuticals, and advanced materials.

Application

• Primary solvent in the determination of cellulose intrinsic viscosity (cupriethylenediamine hydroxide or CED method).
• Research and development of cellulose-based polymers and derivatives.
• Quality control and specification testing for dissolving pulp and regenerated cellulose products (e.g., viscose, lyocell).
• Analytical reagent for studying the molecular weight and degree of polymerization of natural polymers.
• Potential catalyst or complexing agent in specialized organic synthesis.
• Used in the study of copper-amine complexes in coordination chemistry.

Quality Control

Our Cupriethylenediamine is manufactured under strict quality protocols to ensure batch-to-batch consistency and reliability for critical analytical applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as copper content, ethylenediamine concentration, and solution stability. Our quality system is designed to meet the rigorous demands of industrial and research laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its alkaline nature and light sensitivity, prolonged exposure to air, moisture, or light should be avoided to maintain solution integrity and potency.
