Description

Dimethyl (2-Oxo-5-Phenylpentyl)Phosphonate is a specialized organophosphorus compound that serves as a valuable synthetic intermediate in advanced organic chemistry. Its primary value lies in its role as a key building block for the synthesis of complex molecules, particularly through reactions like the Horner-Wadsworth-Emmons olefination. This product is essential for research and development chemists and process engineers in the pharmaceutical and fine chemical industries who require high-purity intermediates for constructing active pharmaceutical ingredients (APIs) and other high-value compounds.

Application

• Pharmaceutical Intermediate: A crucial precursor in the multi-step synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Fine Chemical Synthesis: Used as a specialized reagent for constructing carbon-carbon double bonds via the Horner-Wadsworth-Emmons reaction, enabling the production of α,β-unsaturated carbonyl compounds.
• Agrochemical Research: Employed in the development and research of novel pesticides and herbicides where specific phosphonate chemistry is required.
• Academic & Industrial R&D: Serves as a key starting material in research laboratories for methodological development and the synthesis of novel organic compounds for material science and medicinal chemistry.
• Chemical Library Building: Utilized in combinatorial chemistry and parallel synthesis for creating diverse compound libraries for screening purposes.

Quality Control

Our Dimethyl (2-Oxo-5-Phenylpentyl)Phosphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for synthetic intermediates. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC or NMR), identity (by IR), and impurity profiles are available for every lot and provided upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong bases and incompatible materials.
