??? ??

Colorless to yellow liquid. Readily hydrolyzed by moisture with the liberation of hydrogen chloride. Combustible.

??

Intermediate for silicones.

?? ??

A colorless to yellow liquid with a pungent odor. Amyltrichlorosilane (mixed isomers)(Pentyltrichlorosilane) is combustible and has a flash point of 145°F. Corrosive to metals and tissue.

?? ???

Chlorosilanes, such as Amyltrichlorosilane (mixed isomers)(Pentyltrichlorosilane), 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.

???

Toxic and corrosive.

????

Inhalation causes irritation of mucous membrane. Contact of liquid with eyes or skin causes severe burns, and ingestion causes severe burns of mouth and stomach.

Safety Profile

Moderately toxic by ingestion and skin contact. Mildly toxic by inhalation. A corrosive irritant to the eyes, skin, and mucous membranes. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES

??? ??

It is used to make silicones.

?? ??

UN1728 Amyltrichlorosilane, Hazard class: 8; Labels: 8-Corrosive material.

? ???

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Chlorosilanes react vigorously with bases and both organic and inorganic acids generating toxic and/or flammable gases. Chlorosilanes react with water, moist air, or steam releasing heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks metals in the presence of moisture.
