For professionals working with specialty chemicals, a thorough understanding of a compound's properties and safe handling procedures is critical. Octadecyl Diisopropyl Chlorosilane (CAS 162578-85-0) is an organosilicon compound with distinct characteristics that dictate its applications and how it should be managed. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier, is committed to providing not only high-quality Octadecyl Diisopropyl Chlorosilane but also the necessary information for its effective and safe use.

Key Physical and Chemical Properties of C24H51ClSi

Octadecyl Diisopropyl Chlorosilane (molecular formula: C24H51ClSi; molecular weight: 403.2) is characterized by its physical state and chemical reactivity:

  • Appearance: It is typically supplied as a clear liquid. This physical form makes it convenient for many handling and application processes, such as dispensing and mixing.
  • Reactivity: As a chlorosilane, it is reactive with moisture, protic solvents (like water and alcohols), and nucleophiles. This reactivity is the basis for its utility in surface modification and material synthesis. It will hydrolyze in the presence of moisture, so proper storage and handling are essential.
  • Hydrophobicity: The long C18 octadecyl chain confers significant hydrophobic properties to the molecule, making it ideal for applications requiring water repellency.
  • Purity: Available from reputable suppliers, typically at purities of 95% or higher, ensuring consistent performance in demanding applications. When you plan to buy, always confirm the assay.

Safe Handling and Storage Recommendations

Given its reactive nature, particular care must be taken when handling and storing Octadecyl Diisopropyl Chlorosilane:

  1. Moisture Sensitivity: It is crucial to protect the compound from atmospheric moisture. Store in tightly sealed containers, preferably under an inert atmosphere (like nitrogen or argon) if long-term storage is required. Handling should be done in dry environments.
  2. Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves (e.g., nitrile or neoprene), safety goggles or a face shield, and protective clothing. Work in a well-ventilated area or under a fume hood.
  3. Incompatibility: Avoid contact with strong oxidizing agents, strong acids, and bases, as well as moisture.
  4. Fire Safety: While specific flash point data may vary, chlorosilanes can be flammable. Keep away from heat, sparks, and open flames. Have appropriate fire extinguishing media readily available.
  5. Disposal: Dispose of waste material in accordance with local, regional, and national environmental regulations. Consult the Safety Data Sheet (SDS) for detailed information.
