Phenyltrichlorosilane CAS 98-13-5 Purity >99.0% (GC)

Phenyltrichlorosilane (Trichlorophenylsilane) (CAS: 98-13-5), is one of the most important monomers of organic silicon in the synthesis of organic silicon resin and compounds containing phenyl silicon. Used to produce phenyl silicone for the paint industry. Used as an intermediate for the manufacture of polysiloxanes and phenyl silicone resins. Can improve thermal stability of other silanes. Used as other silanes and siloxanes intermediates or as hydrophobic additive to other silane coupling. Phenyltrichlorosilane can be used in the development of high-capacitance polymer dielectric for low-voltage organic transistors.
General Description: A colorless liquid with a pungent odor. Flash point 91°F. Decomposed by moisture or water to hydrochloric acid with evolution of heat. Corrosive to metals and tissue.
Reactivity Profile: Chlorosilanes, such as Phenyltrichlorosilane are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.
Health Hazard: Highly toxic; may cause death or permanent injury after short inhalation exposure to small quantity. Chemical burns to all exposed membranes and tissues with severe tissue destruction. Inhalation -- lungs may fill up with fluid or throat may swell causing suffocation. Eyes -- damage to corneas may cause blindness. Delayed: after oral exposure stomach and intestines may perforate or be obstructed by scar tissue.
Potential Exposure: Phenyltrichlorosilane is used to make silicones for water repellants, insulating resins; heat resistant paints; and as a laboratory reagent
