Description

Phosphorothioic Acid S-[2-[[3-(Ethylamino)Propyl]Amino]Ethyl] Ester is a specialized organophosphorus compound featuring a thiophosphoryl (P=S) core linked to a polyamine side chain. This unique bifunctional structure, combining a phosphorus ester with multiple amine groups, makes it a valuable intermediate for synthesizing complex ligands, functional polymers, and biologically active molecules. It is primarily sought by researchers and manufacturers in the agrochemical, pharmaceutical, and specialty polymer industries for applications requiring precise molecular modification and chelation properties.

Application

• Agrochemical Intermediate: Serves as a key precursor in the synthesis of novel insecticides, fungicides, and plant growth regulators that leverage its phosphorus and amine functionalities.
• Pharmaceutical Research: Used as a building block for developing prodrugs, enzyme inhibitors, and metal-chelating agents in medicinal chemistry.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce phosphorus and amine groups into polymers, enhancing flame retardancy, adhesion, or metal-binding capacity.
• Ligand Synthesis: Employed in the preparation of complexing agents and ligands for catalysis, metal extraction, and analytical chemistry.
• Surface Treatment Agent: Utilized in formulations for corrosion inhibitors or adhesion promoters on metal surfaces.
• Chemical Research & Development: A versatile reagent for exploring new synthetic pathways and creating novel chemical entities in R&D laboratories.

Quality Control

Our production of Phosphorothioic Acid S-[2-[[3-(Ethylamino)Propyl]Amino]Ethyl] Ester adheres to stringent internal quality protocols to ensure batch-to-batch consistency and purity. Each lot is characterized using advanced analytical techniques, including NMR, HPLC, and titration methods. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
