Ethylene Urea

Ethylene Urea (2-Imidazolidinone)：

Ethylene Urea (CAS No. 120-93-4), chemically designated as 2-Imidazolidinone, functions as a high-purity cyclic organic intermediate. It serves primarily as a reactive intermediate in fine chemical synthesis and as an effective formaldehyde scavenger in polymer and resin systems. Supplied as a white crystalline powder, it is manufactured for industrial-scale applications requiring tightly controlled impurity profiles and consistent batch-to-batch reactivity.

Chemical & Physical Properties：

Solubility: Highly soluble in water; soluble in hot ethanol; sparingly soluble in non-polar organic solvents such as ether and benzene.

Hygroscopic Nature: Readily absorbs ambient moisture. Strict moisture-barrier packaging is required to prevent agglomeration and caking during storage.

Reactivity: Features active secondary amine functional groups within the five-membered heterocyclic ring, enabling stable N-alkylation, condensation, and cross-linking reactions.

 

Applications：

Textile Finishing Resins: Used to synthesize cyclic reactant resins (such as dimethylol ethylene urea derivatives) applied as durable press and crease-resistant finishes for cellulose and blended fabrics, significantly lowering free formaldehyde release compared to conventional urea-formaldehyde formulations.

Agrochemical Synthesis: Acts as a foundational precursor in the synthesis pathway for specific systemic fungicides and plant protection formulations.

Adhesives & Coatings: Functions as a cross-linking modifier and formaldehyde scavenger in amino resin-based wood adhesives and industrial coatings to enhance thermal stability and chemical resistance.

 

Pharmaceutical Manufacturing Relevance：

Employed as a specialized heterocyclic building block in active pharmaceutical ingredient (API) synthesis routes. Low heavy metal thresholds and controlled impurity profiles ensure compatibility with regulated pharmaceutical synthesis standards and ICH guidelines for intermediate materials.

 

Grade & Quality Requirements:

Industrial Grade (Assay >= 99.0%): Optimized for textile resin production, agrochemical intermediates, and general polymer cross-linking applications.

Synthesis Grade (Assay >= 99.5%): Features enhanced purification parameters, keeping heavy metals (<= 10 ppm) and moisture (<= 0.3%) to strict minimums for sensitive pharmaceutical and fine chemical synthesis.

 

Quality Control：

Every production lot undergoes rigorous analytical testing prior to release. Standard verification methods include:

Assay Quantification: Measured using High-Performance Liquid Chromatography (HPLC) or titration.

Thermal Verification: Melting point range confirmed via capillary melting point apparatus.

Moisture Analysis: Quantified via Karl Fischer titration to ensure compliance with the <= 0.5% threshold, eliminating hydrolytic side reactions during customer processing.

Trace Metal Impurities: Screened via ICP-OES to maintain strict limits on heavy metal content.

 

Technical Documents：

COA (Certificate of Analysis): Issued per individual batch, detailing actual assay, moisture, melting point, and impurity values.SDS (Safety Data Sheet): GHS-compliant document detailing hazard classification, safe handling procedures, personal protective equipment (PPE), and emergency response.

TDS (Technical Data Sheet): Complete physical property matrix, handling instructions, and packaging configurations.

 

Packaging & Storage：
