| Regulatorische Informationen | Chemical: Silane, dichloromethylphenyl-Benzene, (dichloromethylsilyl)- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Benzene, (dichloromethylsilyl)- are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)REACH registered substance: Dichloro(methyl)(phenyl)silane (EC: 205-746-2)Dichloromethylphenylsilane: Does not have an individual approval but may be used under an appropriate group standardThe New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces.

| DOT-Kennzeichnung | Corrosive |
| Brandgefahren | When heated to decomposition, it emits toxic fumes of chlorine-containing compounds. Flammable/combustible materialmay be ignited by heat, sparks, or flames. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire. Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Fire may produce irritating or poisonous gases. Reacts strongly with oxidizing materials. (EPA, 1998)· Combustible material: may burn but does not ignite readily. |
| Brandpotenzial | Flammable, moderate fire riskreacts strongly with oxidizing materials.With a little ammonia, it forms a self-igniting product. /Chlorosilanes/ |
Anwendungen & Verwendung
Verwenden
Dichloromethylphenylsilane is used as a monomer (building block) in the production of silicone polymers or silicone resins. Silicone polymers may be oils, greases and rubbers. It is also used as an intermediate (starting material) in the production of other organosilicon substances. It is a bifunctional reagent for the preparation of methylphenylsilyl derivatives of diols.
