Description

Diethyl Cinnamylphosphonate is a high-purity organophosphorus compound, specifically a phosphonate ester, widely recognized as a key building block in organic synthesis. Its primary value lies in its role as a versatile reagent for the Horner-Wadsworth-Emmons (HWE) olefination reaction, enabling the efficient and stereoselective synthesis of α,β-unsaturated esters and related compounds. 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 constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A crucial reagent for synthesizing drug candidates, particularly those containing styryl or cinnamyl moieties, via Horner-Wadsworth-Emmons olefination.
• Agrochemical Synthesis: Used in the production of active ingredients for crop protection agents, where the introduction of specific alkene functionalities is required.
• Fine Chemical & Specialty Chemical Production: Serves as a building block for fragrances, flavors, and functional materials that incorporate the cinnamyl group.
• Academic & Industrial R&D: Employed in methodological development and the synthesis of novel organic compounds for material science and chemical biology.
• Ligand Precursor: Can be utilized in the preparation of phosphorus-containing ligands for catalysis.
