  • Applications

    Triethyl phosphonoacetate (CAS 867-13-0) is a versatile phosphonate ester used as a building block in organic synthesis. In industry, it is commonly employed in Horner–Wadsworth–Emmons olefinations to prepare α,β-unsaturated esters, enabling vinyl phosphonate intermediates for pharmaceutical and agrochemical synthesis. It also serves as a precursor to vinyl phosphonate monomers and related phosphorus-containing building blocks used in polymer and materials chemistry, including coatings and inks. Additionally, it is used as a reactive intermediate in process development and scale-up, allowing introduction of the phosphonoacetate motif into complex synthetic sequences. As a specialized reagent, it is primarily handled within chemical workflows under appropriate safety and regulatory controls.
