N-ethyl-m-toluidine appears as a light amber liquid. Less dense than water and insoluble in water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used to make other chemicals.
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Aniline and related compounds/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Monitor cardiac rhythm and treat arrhythmias as necessary... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. ... . For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Treat seizures with diazepam (Valium) ... . Use proparacaine hydrochloride to assist eye irrigation... . /Aniline and related compounds/
N-ethyl-meta-toluidine (CAS # 102-27-2) was evaluated for acute oral toxicity in Sprague-Dawley rats (5/sex/group) fed doses of 100, 500, 750, and 1000 mg/kg once by oral gavage. Treatment was associated with mortality consistent with an oral LD50 (with 95% confidence limits) of 787 (585-1058) mg/kg. Only animals of 750 and 1000 mg/kg doses died and all, but 3 rats deceased on Days 4, 5, and 7, died on Days 2 and 3 post-gavage. All surviving rats gained weight. Clinical toxicity was characterized by cyanosis in all but 2 rats of 100 mg/kg doses and 1 of a 500 mg/kg dose. Other pharmacotoxic signs noted in more than 1 treated rat included hypoactivity, wet inguinal and/or discolored fur, discolored paws, redness about the nose, discoloration about the mouth, rough hair coat, dyspnea, diarrhea, ataxia, coldness to touch, dark urine, vocalization, pallor, and dyspnea. Necropsy of decedent rats and rats surviving 14-day post-gavage observation identified no gross pathology among animals of 100 or 500 mg/kg doses. Among rats of higher doses (750, 1000 mg/kg), gross lesions included dark brown, red, and/or mottled lungs; dark brown and/or small spleen; dark brown or pale liver; dark brown heart, red fluid-filled urinary bladder, dark brown kidney, and thymic foci.
