Description

2,5,8,11,14,17,20,23,26-Nonaoxaoctacosan-28-Amine is a high-purity, polyether amine derivative characterized by its unique oligomeric ethylene oxide chain terminated with a primary amine group. This structure is critical for applications requiring water solubility, flexibility, and reactive amine functionality in advanced material synthesis. It is an essential intermediate for manufacturers in the pharmaceutical, specialty polymer, and surface modification industries seeking to enhance product performance through tailored chemical properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its hydrophilic polyether chain can improve solubility and bioavailability.
• Polymer Modification: Serves as a reactive monomer or chain extender in polyurethane, polyurea, and epoxy resin formulations, imparting flexibility and hydrophilicity to the final polymer matrix.
• Surface-Active Agents: Acts as a key building block for non-ionic surfactants and emulsifiers, particularly useful in demanding formulations for agrochemicals and coatings.
• Bioconjugation Linker: Employed in biotechnological applications to functionalize peptides, proteins, or nanoparticles, facilitating stable conjugates for diagnostic and therapeutic uses.
• Crosslinking Agent: Utilized in the production of hydrogels and other crosslinked networks for medical devices or controlled-release systems.
• Catalyst Support Ligand: Can be used to modify catalyst surfaces or complexes in specialty chemical synthesis, improving catalytic activity in aqueous media.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurity profile, and physical parameters are available upon request. We adhere to a quality management system to support applications in regulated industries.

Storage

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