Description

Colorless gas or water-white liquid (below 62 degrees F) with an ammonia-like odor; Note: Shipped as a liquefied compressed gas; [NIOSH]

Sources/Uses

Used in the organic synthesis of dyes, medicines, resins, and other chemicals; Also used in oil refining and as a stabilizer of latex rubber; [Merck Index]

Comments

Liquid causes first degree burns on short exposure. [CHRIS] Corrosive to skin; [Quick CPC] Workers may develop eye irritation and corneal edema. Rabbits with inhalation exposure to 50 ppm have lung and corneal injury, while exposure to 100 ppm causes kidney injury; [ACGIH] Evaporating liquid can cause frostbite; [ICSC] Irritating to eyes and respiratory tract; Inhalation of 70% aqueous solution can cause chemical pneumonitis; [MSDSonline]
