II | [Safety Profile]
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. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [General Description]
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. | [Air & Water Reactions]
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. | [Reactivity Profile]
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. | [Health Hazard]
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. | [Fire Hazard]
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. | [Hazard]
Corrosive to wet skin. | [Potential Exposure]
Chlorophenyltrichlorosilane is used as
an intermediate for silicones manufacture. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
30 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions,
including resuscitation mask) if breathing has stopped and
CPR if heart action has stopped. Transfer promptly to a
medical facility. When this chemical has been swallowed,
get medical attention. If victim is conscious, administer
water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized
paramedic may consider administering a drug or other
inhalation therapy. | [Shipping]
UN1753 Chlorophenyltrichlorosilane, Hazard
class: 8; Labels: 8-Corrosive material.
| [Incompatibilities]
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. | [Description]
Chlorophenyltrichlorosilane is a combustible,colorless to pale yellow liquid. Molecular weight =245.99;Boiling point =230℃; Flash point =123.8℃. Decomposesin water. | [Chemical Properties]
Chlorophenyltrichlorosilane is a combustible,
colorless to pale yellow liquid. | [Waste Disposal]
Disposal of unused product
must be undertaken by qualified personnel who are knowledgeable in all applicable regulations and follow all pertinent safety precautions including the use of appropriate
protective equipment. For proper handling and disposal,
always comply with federal, state, and local regulations.
| [storage]
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. |
