Description

Ethylenediamine Monohydrate is a versatile, high-purity organic compound that serves as a critical building block and reagent in advanced chemical synthesis. Its bifunctional nature, featuring both primary amine groups, makes it an essential precursor for pharmaceuticals, agrochemicals, and high-performance polymers. This product is particularly valued by industries requiring a reliable and consistent source of a pure, hygroscopic diamine for applications ranging from chelating agents to epoxy curing systems.

Application

• Pharmaceutical Intermediate: Key starting material in the synthesis of various active pharmaceutical ingredients (APIs), including certain antibiotics and antimycobacterial agents.
• Chelating Agent Production: Core precursor for manufacturing EDTA (ethylenediaminetetraacetic acid) and related sequestrants used in water treatment, textiles, and personal care products.
• Epoxy Resin Curing Agent: Functions as a cross-linking agent and hardener for epoxy resins, contributing to the thermal and mechanical properties of coatings, adhesives, and composites.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators.
• Corrosion Inhibitor: Employed in formulations for boiler water treatment and metalworking fluids to prevent scale and corrosion.
• Polymer & Fiber Industry: Serves as a monomer or chain extender in the production of polyamides, polyurethanes, and other specialty polymers.
• Analytical Chemistry: Utilized as a reagent in complexometric titrations and as a buffer component.
• Gas Treatment: Acts as an absorbent for acidic gases like CO2 and H2S in natural gas purification and industrial gas scrubbing processes.

Quality Control

Our Ethylenediamine Monohydrate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, water content, and impurity profiles. While we offer standard technical and reagent grades, our processes are designed to meet the stringent requirements of pharmaceutical (GMP) and industrial applications.

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 (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong acids and oxidizing agents.
