| Regulatorische Informationen | Chemical: 2-ThiazolamineStatus: Active Update: 11-12-2017 https://echa.europa.eu/registration-dossier/-/registered-dossier/216532-Aminothiazole: Does not have an individual approval but may be used under an appropriate group standard |
| Brandgefahren | Flash point data for this chemical are not availablehowever, it is probably combustible. (NTP, 1992) |
| Gesundheitsgefahren | SYMPTOMS: Symptoms of exposure to this compound may include nausea, headache and weakness. It may also cause irritation.ACUTE/CHRONIC HAZARDS: This compound may be harmful by ingestion, inhalation or skin absorption. It may cause irritation. When heated to decomposition, it may emit toxic fumes of carbon monoxide, carbon dioxide, NOx and SOx. (NTP, 1992) |
| Reaktive Gruppe | Amines, Phosphines, and PyridinesSulfides, Organic |
| Reactivity Profile | 2-AMINOTHIAZOLE reacts violently when nitrated with nitric or nitric-sulfuric acids. It is also incompatible with strong oxidizing agents, strong acids, acid chlorides and acid anhydrides. (NTP, 1992) |

| Hazard Classes and Categories | Acute Tox. 4 (100%)Eye Irrit. 2A (82.8%)STOT SE 3 (31%) |
| Brandbekämpfung | Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992) |
| Erste Hilfe | EYES: 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.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992) |
| Freisetung ohne Brand | SMALL 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.STORAGE PRECAUTIONS: You should store this chemical under refrigerated temperatures and away from mineral acids and bases. (NTP, 1992) |
| 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) |
