Description

Ethyl Methyl Pent-2-Ene-1,5-Dioate is a specialized diester compound with a reactive alkene backbone, serving as a versatile chemical intermediate. Its value lies in its bifunctional structure, which allows for selective reactions at the ester and alkene sites, enabling the synthesis of complex molecules. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop new active ingredients or functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring a functionalized diacid or diol precursor.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where its unsaturated diester structure introduces specific reactivity.
• Specialty Polymer Monomer: Acts as a monomer or co-monomer for creating polymers with tailored properties, such as cross-linkable resins, coatings, and adhesives.
• Fine Chemical & Fragrance Intermediate: Employed in multi-step organic synthesis to construct complex esters and lactones used in flavors and fragrances.
• Cross-coupling Reactions: Serves as a substrate in palladium-catalyzed cross-coupling reactions (e.g., Heck, Suzuki) due to its reactive alkene functionality.
• Organic Synthesis Reagent: A valuable reagent in academic and industrial research labs for Diels-Alder reactions, Michael additions, and other carbon-carbon bond-forming transformations.

Quality Control

Our Ethyl Methyl Pent-2-Ene-1,5-Dioate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. For long-term storage, consider an inert atmosphere to preserve the alkene functionality.
