Air & Water Reactions
Insoluble in water.
Reactivity Profile
3-ETHYL-3-METHYLGLUTARIMIDE is an amide. 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).
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition it emits toxic fumes.
Fire Hazard
Flash point data for 3-ETHYL-3-METHYLGLUTARIMIDE are not available. 3-ETHYL-3-METHYLGLUTARIMIDE is probably not flammable.
Safety Profile
Poison by ingestion,
intravenous, intraperitoneal, intramuscular,
subcutaneous, and parented routes. Human
systemic effects by ingestion: wakefulness,
hallucinations, distorted perceptions, toxic
psychosis. An analeptic, central nervous
system stimulant; used to counteract
barbiturate poisoning. When heated to
decomposition it emits toxic fumes of NOx.
