Chlorophenyltrichlorosilane is a combustible, colorless to pale yellow liquid.

Intermediate for silicones.

A mixture of isomers.

chlorophenyltrichlorosilane is a colorless to pale yellow liquid with a pungent odor. The material will burn though chlorophenyltrichlorosilane may take some effort to ignite. chlorophenyltrichlorosilane is decomposed by moisture or water to hydrochloric acid with evolution of heat. chlorophenyltrichlorosilane is corrosive to metals and tissue.

Based on the properties of similar materials, there is the possibility that the reaction of chlorophenyltrichlorosilane with water may be vigorous or violent. Products of the reaction include hydrogen chloride. The reaction generates heat and this heat may be sufficient to ignite the product.

Chlorosilanes, such as chlorophenyltrichlorosilane, 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.

Corrosive to wet skin.

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

A poison irritant by ingestion and inhalation. A corrosive irritant to the skin, eyes, and mucous membranes. Combustible when exposed to heat or flame. In contact with water it readily hydrolyzes to HCl and evolves heat. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES.

Chlorophenyltrichlorosilane is used as an intermediate for silicones manufacture.

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least30 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting.Medical observation is recommended for 2448 h afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray.

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with chlorophenyltrichlorosilane you should betrained on its proper handling and storage.Chlorophenyltrichlorosilane should be stored to avoid contact with combustible materials, such as wood, paper, andoil. Store in tightly closed containers in a cool, well-ventilated area away from water, steam, and moisture becausetoxic and corrosive gases, including hydrogen chloride, canbe produced.

UN1753 Chlorophenyltrichlorosilane, 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 to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks metals in the presence of moisture. Keep chlorophenyltrichlorosilane away from combustible materials, such as wood, paper, and oil. Chlorophenyltrichlorosilane reacts with α-ketoacids, forming heterocyclic compounds of quinoxalones.
