Category |
Amines, Aliphatic |
Description |
Colorless liquid with an ammonia-like odor; Note: A gas above 91 degrees F; [NIOSH] |
Sources/Uses |
Used as a solvent and as an intermediate in the synthesis of dyes, rubber additives, pesticides, surface active agents, and pharmaceuticals; [ACGIH] |
Comments |
Liquid causes first degree burns on short exposure. [CHRIS] Corrosive to skin; [Quick CPC] Acute animal toxicology studies indicate that inhaled isopropylamine has a potency about one half that of n-butylamine. It causes respiratory irritation, and can cause pulmonary edema. [ACGIH] Halo vision and other visual disturbances usually resolve within 24 hours. [CHEMINFO] |
