CAS 1000-50-6

Butyldimethylsilyl chloride

Description:

Butyldimethylsilyl chloride, with the CAS number 1000-50-6, is an organosilicon compound characterized by the presence of a butyl group and two methyl groups attached to a silicon atom, along with a chloride functional group. It is typically a colorless to pale yellow liquid with a distinctive odor. This compound is known for its reactivity, particularly as a silylating agent in organic synthesis, where it is used to protect hydroxyl groups in alcohols and phenols during various chemical reactions. Butyldimethylsilyl chloride is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water due to its hydrophobic nature. It is important to handle this compound with care, as it can be corrosive and may cause irritation to the skin and eyes. Additionally, it should be stored in a cool, dry place away from moisture and incompatible substances to maintain its stability and effectiveness in chemical applications.

Alkyl 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.
