Description

(E)-3-Formylbut-2-Enyl Acetate is a versatile α,β-unsaturated ester aldehyde, a bifunctional molecule that serves as a valuable intermediate in fine chemical synthesis. Its unique structure, featuring both an aldehyde and an acetate group on a conjugated diene system, makes it a key building block for constructing complex molecular frameworks. This compound is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fragrance industries for applications in cycloaddition reactions, nucleophilic additions, and as a precursor to various heterocycles.

Application

• Pharmaceutical Intermediate: A crucial synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the construction of lactones, pyrans, and other oxygen-containing heterocycles via cyclization reactions.
• Agrochemical Synthesis: Used in the production of advanced crop protection agents, where its reactive sites allow for the introduction of specific functional groups into pesticide and herbicide molecules.
• Fragrance and Flavor Chemistry: Acts as a precursor for aroma chemicals, contributing to green, fruity, or floral notes through subsequent chemical transformations.
• Material Science Research: Employed as a monomer or cross-linking agent in polymer research for creating novel resins and functional materials with specific properties.
• Organic Synthesis Building Block: Utilized in Diels-Alder reactions, Michael additions, and other C-C bond-forming processes to create complex organic molecules in academic and industrial research settings.
• Chemical Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our (E)-3-Formylbut-2-Enyl Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (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 preservation. Keep away from heat, sparks, and open flames.
