Description

Triethylenetetramine Disulfate Dihydrate is a specialized salt form of the versatile chelating agent triethylenetetramine. This compound is valued for its enhanced stability and handling properties compared to the free base, making it a critical intermediate and reagent in advanced chemical synthesis. It is primarily sought by manufacturers in the pharmaceutical, polymer, and specialty chemical industries for applications requiring precise amine functionality and controlled reactivity.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring polyamine backbones or as a precursor for chelating agents in medicinal chemistry.
• Epoxy Curing Agent Precursor: Serves as a key raw material for producing modified amine-based hardeners and cross-linking agents for epoxy resin systems.
• Chelating Agent Synthesis: Acts as a fundamental building block for manufacturing advanced sequestering agents used in water treatment, textile processing, and metal finishing.
• Polymer Modification: Employed to introduce amine functional groups into polymer chains, enhancing properties like adhesion, dyeability, and chemical resistance.
• Corrosion Inhibitor Formulation: A component in specialty formulations designed to protect metal surfaces in industrial cooling systems and boiler water treatments.
• Research & Development: Utilized in organic synthesis and material science research as a standardized source of triethylenetetramine.

Quality Control

Our Triethylenetetramine Disulfate Dihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, purity, and related substances is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture, which can affect product stability and handling.
