    Product Description

    Chloromethylmethyldiisopropoxysilane is a bifunctional organosilicon intermediate identified by CAS 2212-08-0 and EC/EINECS 630-736-3.

    Synonyms: Chloromethyl(diisopropoxy)methylsilane; (Chloromethyl)methyldiisopropoxysilane; Methyl(chloromethyl)diisopropoxysilane.

    CAS: 2212-08-0.

    Molecular formula: C₈H₁₉ClO₂Si.

    Molecular weight: 210.78.

    EC number: 630-736-3.

    It contains a chloromethyl group for nucleophilic substitution and two isopropoxy groups for controlled hydrolysis, surface silanization and polymer crosslinking.

    It is used as a reactive silane intermediate in specialty silicone, coupling-agent and surface-modification applications.

    Typical uses include adhesion promotion, silanization, resin modification, sealant production and advanced textile finishing.

    The isopropoxy groups can hydrolyze on contact with water; keep the material dry to preserve reactivity and avoid premature condensation.

    Typical properties include boiling point about 177.5 °C, flash point about 67.8 °C, density about 0.952 g/cm³, and refractive index about 1.4212.

    FAQ - Technical & Supply Chain

    • Q:

      What is Chloromethylmethyldiisopropoxysilane CAS 2212-08-0?

      A: Chloromethylmethyldiisopropoxysilane is a bifunctional organosilicon intermediate with molecular formula C₈H₁₉ClO₂Si. It contains a chloromethyl group for nucleophilic substitution and two isopropoxy groups for controlled hydrolysis, surface silanization and polymer crosslinking.
    • Q:

      Why is CAS 2212-08-0 used instead of 18171-11-4 for this product?

      A: The compound name Chloromethylmethyldiisopropoxysilane and its molecular formula C₈H₁₉ClO₂Si correspond to CAS 2212-08-0. CAS 18171-11-4 is a different monoisopropoxy silane, so the corrected identifier avoids confusion with the dimethyl-isopropoxy analog.
    • Q:

      What is Chloromethylmethyldiisopropoxysilane used for?

      A: It is used as a reactive silane intermediate in specialty silicone, coupling-agent and surface-modification applications. Typical uses include adhesion promotion, silanization, resin modification, sealant production and advanced textile finishing.
    • Q:

      Why is moisture control important for Chloromethylmethyldiisopropoxysilane?

      A: The isopropoxy groups can hydrolyze on contact with water and form silanol species, which may then condense. Keeping the material dry helps preserve reactivity, avoid premature polymerization and maintain the required silane performance.
    • Q:

      How should Chloromethylmethyldiisopropoxysilane be stored and handled?

      A: Store it in tightly closed, dry containers in a cool, ventilated area away from moisture, water, strong acids, bases and oxidizers. Use chemical-resistant PPE, avoid unnecessary exposure and follow applicable flammable-liquid and spill-handling requirements.
