Description

Diethyl(Methanesulfonyloxymethyl)Phosphonate, 97 % is a high-purity organophosphorus reagent primarily used as a key intermediate in organic synthesis. Its value lies in its role as a Horner-Wadsworth-Emmons (HWE) reagent, enabling the efficient construction of carbon-carbon double bonds, particularly in the synthesis of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Critical for synthesizing alkenes and α,β-unsaturated carbonyl compounds found in active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Material Science Research: Serves as a building block for creating novel polymers, ligands, and functional organic materials.
• Academic & R&D Laboratories: A versatile reagent for method development and exploring new synthetic pathways in organic chemistry.
• Fine Chemical Production: Employed in the multi-step synthesis of flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Diethyl(Methanesulfonyloxymethyl)Phosphonate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and GC analysis, to verify identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
