    Vinylcyclopentane CAS 3742-34-5

    Vinylcyclopentane is a hydrocarbon compound consisting of a cyclopentane ring substituted with a vinyl group, combining alicyclic and olefinic structural features within a single molecule. This structural arrangement defines its classification as a specialty unsaturated hydrocarbon within professional chemical supply chains. Vinylcyclopentane (CAS 2546-38-5) is handled as a defined molecular substance in regulated industrial and research environments, with emphasis on material identification, documentation, and compliance rather than end‑use formulation.
    This material is supplied with standardized specifications and complete technical documentation including MSDS, TDS, and COA, supporting compliant handling and traceability.

    Application Areas

    Organic synthesis intermediates: can be used to prepare polymers, drug molecules, or functional materials, and participate in coupling reactions or cycloaddition reactions.
    Industrial solvents: Due to their low boiling point (97 ℃) and solubility, they may be used in coatings, inks, or cleaning agent formulations

    Storage conditions

    Temperature and sealing: Store in a cool and ventilated place at 2-8 ℃, and strictly seal the container to prevent volatilization.
    Light avoidance and stability: stored in the dark, chemically stable at room temperature and pressure, but kept away from oxidants and strong acids

    Safety precautions

    Health hazards
    Flammability: Highly flammable liquids and vapors should be kept away from sources of fire, heat, and static sparks.
    Irritation: May cause irritation to the skin, eyes, and respiratory tract. Protective equipment (gloves, goggles, etc.) should be worn.
    Operation and emergency measures
    Leakage treatment: Use inert materials to adsorb and avoid entering the sewer.
    Extinguishing method: use dry powder, carbon dioxide or foam extinguisher, and do not spray water directly
