Description

1,19-Diamino-4,7,10,13,16-Pentaoxa-Nonadecane is a specialized polyether diamine compound, identified by CAS number 869308-34-9. This molecule is valued for its unique bifunctional structure, combining a hydrophilic polyether spacer with reactive primary amine termini, making it a versatile building block for advanced material synthesis. It is essential for researchers and manufacturers in the polymer, pharmaceutical, and specialty chemical industries seeking to create custom-tailored materials with specific properties.

Application

• Polymer Modification & Crosslinking Agent: Used to introduce hydrophilic segments and reactive sites into polyurethanes, epoxies, and other polymers to modify flexibility, solubility, and reactivity.
• Pharmaceutical Intermediate: Serves as a key synthon for constructing drug delivery systems, such as dendrimers and polymer-drug conjugates, due to its biocompatible polyether chain and amine handles.
• Surface-Active Agent Synthesis: A precursor for creating non-ionic surfactants and emulsifiers with specific hydrophilic-lipophilic balance (HLB) values.
• Chelating Ligand Precursor: The polyether backbone and amine groups can be functionalized to create ligands for metal ion complexation in catalysis or extraction processes.
• Hydrogel Formation: Employed in the synthesis of cross-linked, water-absorbent polymer networks for biomedical and agricultural applications.
• Adhesive & Sealant Formulations: Imparts improved adhesion and moisture resistance when incorporated into specialty adhesive systems.

Quality Control

Our 1,19-Diamino-4,7,10,13,16-Pentaoxa-Nonadecane is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent molecular weight distribution, and the absence of critical impurities. Certificates of Analysis (COA) detailing specifications such as assay, amine value, water content, and color are available upon request. We support compliance with relevant standards for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and moisture absorption.
