| 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. |
| Freisetung ohne Brand | SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces 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. |
Anwendungen & Verwendung
Beschreibung
5-Sulfoanthranilic acid is produced from anthranilic acid by sulfonation with chlorosulfuric acid in anhydrous sulfuric acid or nitrobenzene or by baking the sulfate of anthranilic acid at 200 ℃. This compound is used, like its N-alkyl derivatives, as a stabilizer for diazo compounds.
