Description

Ethyleneimine (Aziridine) is a highly reactive, versatile heterocyclic amine that serves as a critical building block in organic synthesis and polymer chemistry. Its strained three-membered ring structure makes it a powerful alkylating agent, enabling the introduction of aminoethyl groups into a wide range of molecules. This compound is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to create advanced materials, functional coatings, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediates: Key precursor in the synthesis of various drugs, including anticancer agents, antibiotics, and other nitrogen-containing therapeutics.
• Polymer & Resin Modification: Used to produce polyethylenimine (PEI), a cationic polymer with applications in paper strengthening, water treatment, and as a flocculant.
• Agrochemical Synthesis: Intermediate in the manufacture of certain herbicides, fungicides, and plant growth regulators.
• Crosslinking Agent: Imparts durability and chemical resistance in the production of specialty coatings, adhesives, and textile finishes.
• Ion-Exchange Resins: Functional monomer for creating resins used in water purification and chromatography.
• Bioconjugation & Protein Modification: Employed in biochemical research for labeling and modifying biomolecules.

Quality Control

Our Ethyleneimine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We adhere to relevant industry standards and can provide material tailored to specific application requirements, including research and industrial grades.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and temperatures should be maintained as recommended on the specific material safety data sheet (MSDS).
