Specification
Butyltrichlorosilane (CAS NO.7521-80-4) is a colorless liquid with a pungent odor. It is corrosive to metals and skin. It reacts with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride and flammable butane. Can serve as a chlorination agent. Reacts vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. Reacts with alcohols, acetone and light metals. Inhalation of vapor irritates upper respiratory system. Contact of liquid with eyes or skin causes severe burns. Ingestion causes burns of mouth and stomach.
