Description

3,6,9,12-Tetraoxatridecylamine is a specialized polyether amine surfactant and chemical intermediate. This compound is valued for its unique structure, which combines a hydrophilic polyether chain with a reactive primary amine group, offering excellent solubility and surface-active properties. It is primarily utilized in the formulation of advanced materials, including epoxy curing agents, polyurethane catalysts, and specialty surfactants for industrial and research applications.

Application

• As a curing agent or hardener in epoxy resin systems, modifying flexibility and reactivity.
• As a catalyst or chain extender in polyurethane (PU) and polyurea formulations.
• As a key intermediate in the synthesis of specialty surfactants and demulsifiers for the oil & gas industry.
• In the production of quaternary ammonium compounds for use as biocides or fabric softeners.
• As a corrosion inhibitor component in functional fluids and coatings.
• In the manufacture of pharmaceutical and agrochemical intermediates requiring polyether-linked amines.
• For research and development of novel polymers and surface-active agents.

Quality Control

Our 3,6,9,12-Tetraoxatridecylamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, water content, and color. We support compliance with relevant global chemical regulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
