    1-Chloro-2-methyl-1-cyclohexene CAS 16642-49-2

    1-Chloro-2-methyl-1-cyclohexene is a chlorinated cyclic olefin used as an organic synthesis intermediate, commonly participating in substitution, elimination, and coupling reactions within controlled chemical processes. As a structurally defined chloroalkene (CAS 16642-49-2), it provides a reactive vinyl chloride functionality suitable for downstream transformation in fine chemical and specialty intermediate synthesis where cyclic frameworks are required. Industrial supply is available with competitive factory pricing, support for customized specifications, and complete documentation including MSDS, TDS, COA, enabling bulk supply for standardized manufacturing operations.

    Application Areas

    Organic synthesis: as a halogenated olefin intermediate, used for the preparation of drugs, pesticides, and fine chemicals
    Research purpose: As a functional reaction substrate in the study of cyclohexene derivatives

    Storage conditions

    Environmental requirements: Store in a cool, ventilated warehouse, away from fire and heat sources, and the temperature should not exceed 30 ℃
    Packaging specification: Sealed and stored in glass or corrosion-resistant plastic containers, avoiding direct contact with metal
    Isolation measures: Store separately from oxidants, strong acids and bases to prevent reaction risks

    Safety precautions

    Health risks: Inhalation or skin contact may cause respiratory irritation and dermatitis. Gas masks and chemical protective gloves should be worn during operation
    Avoid long-term exposure as it may inhibit the central nervous system
    Leakage treatment: Collect after adsorption with sand, do not rinse with water
    Handling of accidental contact: Immediately wash with soapy water after skin contact, rinse with physiological saline for 15 minutes for eye contact, and seek medical attention
    Disposal: Dispose of according to hazardous chemical regulations and do not discharge at will

    FAQ - Technical & Supply Chain

    • Q:

      Do CAS 16642-49-2 and CAS 13346-60-6 refer to the same substance?

      A: They are used in industry and databases to describe the same structural type of 1‑chloro‑2‑methylcyclohexene, with CAS 16642-49-2 more commonly applied as the primary reference.
    • Q:

      Is 1-Chloro-2-methyl-1-cyclohexene intended for industrial intermediate use?

      A: It is typically used as an intermediate in organic and fine chemical synthesis, rather than as a finished or consumer-facing product.
