Propargyl bromide

Propargyl bromide, also known as 3-bromo-prop-1-yne, is an organic compound with the chemical formula HC≡CCH2Br.

A colorless liquid, it is a halogenated organic compound consisting of propyne with a bromine substituent on the methyl group.

Propargyl bromide can also be used as an intermediate for the synthesis of organic compounds, including agrochemicals and pharmaceuticals.

[7] Propargyl bromide is a lachrymator and an alkylating agent,[8] This liquid acetylenic endothermic compound may be decomposed by mild shock, and when heated under confinement, it decomposes with explosive violence and may detonate.

Addition of 20—30 wt% of toluene makes propargyl bromide insensitive in laboratory impact and confinement tests.

E.g. chlorine gas Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasoline Instability 4: Readily capable of detonation or explosive decomposition at normal temperatures and pressures. E.g. nitroglycerin Special hazards (white): no code
