01 · Identification
What Allylamine is
Allylamine is a colorless to light yellow liquid with strong ammonia odor causing sneezing and tears. Its molecular formula is C3H7N and its molecular weight is 57.09 g/mol. It boils at 53.5 °C, melts at -88.2 °C.
Under the GHS it carries the signal word Danger. It is classed as flammable agents - 3rd degree.

04 · Source notes
Further notes on Allylamine
These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.
Odor
The odor threshold is reportedly 14.5 mg/cu m, and the odor becomes irritating at approximately 187 mg/cu m. The odor is that of strong ammonia, which is recognizable at 2.5 ppm.

05 · Handling and storage
Storing and handling Allylamine
Storage conditions
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store under inert gas. Storage class (TRGS 510): Flammable liquids.

Reactivity
ALLYLAMINE reacts violently with strong oxidizing agents and acids. Attacks copper and copper compounds [Handling Chemicals Safely 1980. p. 123]. Reacts with hypochlorites to give N-chloroamines, some of which are explosives when isolated [Bretherick 1979. p. 108].
