    SolubilityInsoluble in water; soluble in organic solvents such as ethanol, diethyl ether, and chloroform
    Chemical StructureContains a double bond between carbon atoms 2 and 3, with two chlorine atoms attached to carbon atom 1 and a methyl group attached to carbon atom 3

    Application Areas

    Organic synthesis intermediates: commonly used for synthesizing other complex organic compounds, such as silane derivatives.
    Chemical research: used to study the kinetics of ozone reaction and the reaction mechanism with reagents such as potassium iodide

    Storage conditions

    Temperature control: It is recommended to store in a low temperature environment of 2-8 ° C to avoid decomposition caused by high temperatures.
    Stabilizer addition: Potassium carbonate (K ₂ CO ∝) needs to be added as a stabilizer to prevent decomposition.
    Isolation measures: Keep away from oxidants, open flames, and heat sources, and store in a ventilated and dry place

    Safety precautions

    Toxicity protection: It belongs to the low toxicity category, but inhaling high concentration vapors may cause kidney damage. Self contained respirators should be worn during operation.
    Leakage handling:
    Minor leakage: Use sand or non combustible materials to adsorb and dispose of.
    Large amount of leakage: build a dike to receive, and cover with foam to reduce vapor diffusion.
    Fire fighting measures: use dry powder, carbon dioxide or foam to extinguish the fire and avoid splashing caused by direct water.

    FAQ - Technical & Supply Chain

    • Q:

      Is 1,1-Dichloro-3-methyl-2-butene a single, well-defined substance?

      A: Yes. It is a distinct chlorinated olefin with a specific molecular structure and a single CAS registration.
    • Q:

      Is this compound mainly intended for use as an intermediate rather than a finished product?

      A: It is typically supplied as an intermediate for organic and fine chemical synthesis under controlled industrial conditions.
