CAS 768-33-2

Chlorodimethylphenylsilane

Description:

Chlorodimethylphenylsilane, with the CAS number 768-33-2, is an organosilicon compound characterized by the presence of a silicon atom bonded to two methyl groups, one phenyl group, and one chlorine atom. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the chlorine substituent, which can participate in various chemical reactions, including nucleophilic substitution and cross-coupling reactions. Chlorodimethylphenylsilane is often utilized in the synthesis of silane-based materials, as well as in surface modification processes, where it can enhance adhesion and hydrophobic properties. It is also used in the production of silicone polymers and as a coupling agent in various applications. Safety precautions are necessary when handling this compound, as it can be irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and reactivity.

Phenyl-Containing Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
Aromatic Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
