Description

Tetraethyl Vinylidene Phosphonate, Min. 97 % is a high-purity organophosphorus compound characterized by its vinylidene and phosphonate ester functional groups. This structure makes it a versatile and reactive intermediate for synthesizing complex molecules and advanced materials. It is primarily sought after by research chemists and process development teams in the agrochemical and pharmaceutical industries for creating novel active ingredients and functional polymers.

Application

• Agrochemical Intermediate: A key building block for the synthesis of novel insecticides, herbicides, and plant growth regulators, leveraging its reactive vinylidene group for further functionalization.
• Pharmaceutical Research: Used in medicinal chemistry as a precursor for prodrugs or bioactive molecules containing phosphonate groups, which can mimic biological phosphates.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the production of specialty polymers, flame retardants, and coatings with tailored properties.
• Ligand Synthesis: Employed in the preparation of organophosphorus ligands for catalysis and metal complexation in homogeneous catalytic processes.
• Chemical Synthesis: Acts as a Michael acceptor or a substrate in Horner-Wadsworth-Emmons (HWE) olefination reactions to construct carbon-carbon double bonds.
• Flame Retardant Formulations: Can be incorporated as a reactive component in polymeric materials to enhance flame retardancy due to its phosphorus content.
