Description

3,6,9,12,15,18,21,24,27,30,33-Undecaoxatetratriacontan-1-Amine is a high-purity, long-chain polyether amine, a versatile building block for advanced material synthesis. Its unique structure, featuring a terminal amine group linked to a poly(ethylene glycol) chain, provides exceptional solubility, reactivity, and functionalization capabilities. This compound is essential for researchers and manufacturers in the pharmaceutical, polymer, and specialty chemical industries seeking to develop novel surfactants, linkers, and functional polymers.

Application

• Pharmaceutical Intermediates: Used as a functional linker or spacer in the synthesis of prodrugs, antibody-drug conjugates (ADCs), and targeted drug delivery systems.
• Polymer Modification: Serves as a reactive monomer or chain extender for producing polyurethanes, polyamides, and epoxy resins with enhanced flexibility, hydrophilicity, and biocompatibility.
• Surface-Active Agents: Acts as a key component in the formulation of non-ionic surfactants and emulsifiers for agrochemicals, coatings, and personal care products.
• Bioconjugation Chemistry: Utilized for PEGylation (polyethylene glycol modification) of peptides, proteins, and other biomolecules to improve solubility, stability, and circulation time.
• Crosslinking Agent: Employed in the creation of hydrogels, networks, and functional coatings that require water-soluble, amine-reactive crosslinkers.
• Catalyst and Ligand Synthesis: Functions as a precursor for creating specialized ligands and catalysts used in organic synthesis and industrial processes.

Quality Control

Our 3,6,9,12,15,18,21,24,27,30,33-Undecaoxatetratriacontan-1-Amine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and assay, NMR and IR for structural confirmation, and Karl Fischer titration for water content, to ensure it meets exacting specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) and desiccate upon opening to prevent moisture uptake and degradation.
