Description

4-Ethenyloxan-4-ol is a versatile oxane derivative featuring both a vinyl and a hydroxyl functional group on the same carbon atom. This unique bifunctional structure makes it a valuable intermediate in advanced organic synthesis, particularly for constructing complex heterocyclic frameworks and functional polymers. It is primarily sought by research and development chemists in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel drug candidates, especially those containing tetrahydrofuran or tetrahydropyran motifs.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Serves as a functional monomer or cross-linking agent for specialty polymers, including coatings, adhesives, and resins.
• Organic Synthesis Reagent: Employed in academic and industrial R&D for cyclization reactions and the introduction of chiral centers.
• Ligand and Catalyst Development: Potential precursor for creating novel ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Flavor and Fragrance Industry: Intermediate for the synthesis of complex odorants and flavoring agents with oxane structures.

Quality Control

Our 4-Ethenyloxan-4-ol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP and ISO 9001 standards for research and industrial applications.

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 hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Store away from incompatible materials such as strong oxidizing agents.
