Description

Diethyl-3-Butenylphosphonate 95 is a high-purity organophosphorus compound, specifically a phosphonate ester, widely used as a versatile building block in organic synthesis. Its primary value lies in its role as a key reagent in the Horner-Wadsworth-Emmons (HWE) olefination reaction, enabling the efficient and stereoselective synthesis of α,β-unsaturated carbonyl compounds. This makes it an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical reagent in the synthesis of complex drug molecules, particularly for constructing alkene linkages in active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and plant growth regulators that require specific alkene functionalities.
• Specialty Chemical Manufacturing: Serves as a key precursor for synthesizing fine chemicals, flavors, fragrances, and functional monomers.
• Material Science Research: Employed in the development of novel polymers, ligands for catalysis, and organic electronic materials.
• Academic & R&D Laboratories: A staple reagent for methodological development in organic chemistry and for the synthesis of complex natural product analogs.
