Each notification may be associated with multiple companies.
Regulatorische InformationenChemical: Benzenesulfonamide, N-ethyl-4-methyl-Benzenesulfonamide, N-ethyl-4-methyl- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Benzenesulfonamide, N-ethyl-4-methyl- 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)Benzenesulfonamide, N-ethyl-4-methyl-: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.
BrandgefahrenFlash point data for this chemical are not availablehowever, it is probably combustible. (NTP, 1992)
GefahrenübersichtA skin and strong eye irritant[Sigma-Aldrich MSDS] See Toluenesulfonamide.
Reaktive GruppeAmines, Phosphines, and Pyridines
Reactivity ProfileAn amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Air and Water ReactionsInsoluble in water.
Hazard Classes and CategoriesSkin Irrit. 2 (72.6%)
BrandbekämpfungFires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Erste HilfeEYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Freisetung ohne BrandSMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Personal Protective Equipment (PPE)RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)
