Description

Diethyl trans-Cinnamylphosphonate is a high-purity organophosphorus compound, specifically a phosphonate ester, widely used as a key reagent in organic synthesis. Its primary value lies in its role as a versatile building block for the stereoselective construction of carbon-carbon double bonds via the Horner-Wadsworth-Emmons (HWE) olefination reaction. This product is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable, high-quality intermediates for complex molecule synthesis.

Application

• Pharmaceutical Intermediate: A critical reagent for the synthesis of biologically active molecules, including drug candidates with unsaturated side chains.
• Agrochemical Synthesis: Used in the production of pesticides and herbicides that incorporate cinnamyl or styryl motifs.
• Fine Chemical Production: Serves as a precursor for fragrances, flavors, and specialty chemicals requiring the introduction of an α,β-unsaturated ester moiety.
• Material Science Research: Employed in the development of novel polymers and organic electronic materials through controlled olefination reactions.
• Academic & R&D Laboratories: A staple reagent for methodological development in organic chemistry and the synthesis of complex natural product analogs.
