Acetaldehyde ammonia is a white crystalline solid and very soluble in water. It is used to make other chemicals and vulcanise rubber. On long exposure to air, acetaldehyde ammonia oxidises, hardens, and turns yellow or brown in colour and reacts exothermically with water to evolve gaseous ammonia. Acetaldehyde ammonia reacts with strong oxidising agents and halogens, and when heated, it readily decomposes into acetaldehyde and ammonia. It attacks copper, aluminium, zinc, and their alloys and reacts with mercury and silver oxides to form shock-sensitive compounds.

R20/21/22:Harmful by inhalation, in contact with skin and if swallowed .
R36/37/38:Irritating to eyes, respiratory system and skin .

S26:In case of contact with eyes, rinse immediately with plenty of water and seek medical advice .
S36/37/39:Wear suitable protective clothing, gloves and eye/face protection .

It readily decomposes into acetaldehyde and ammonia when heated, causing the hazards of these substances. Moderate fire and explosion hazard when exposed to heat or flame. Can react with oxidizing materials. When heated to decomposition it emits toxic fumes of NH3 and NOx
