Diamond Hazard Value Description
3 4
Health   3 Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid)
Flammability   3 Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions . Liquids having a flash point below 22.8 °C (73 °F) and having a boiling point at or above 37.8 °C (100 °F) or having a flash point between 22.8 and 37.8 °C (73 and 100 °F). (e.g. gasoline, acetone)

3-Bromopropyne Chemical Properties,Uses,Production

Chemical Properties

yellow solution


Used to make propargylic amines employed in enyne metathesis.1Employed in the propargylation of spiro ketones,2 allylic alcohols,3 and enone complexes.4

General Description

A colorless to light yellow liquid substance with a sharp odor. Flash point 65°F. Denser than water and insoluble in water. Vapors are heavier than air. May be irritating to skin and eyes. Used to make other chemicals. 3-Bromopropyne may decompose explosively with mild shock.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

3-Bromopropyne is soluble in alcohol, ether, chloroform, carbon tetrachloride and carbon disulfide. 3-Bromopropyne is highly flammable and a dangerous fire risk, sensitive to shock. 3-Bromopropyne is used in organic syntheses, preparation of resins and perfume intermediates [Hawley]. There is a high danger of formation of explosive metal acetylides, when 3-Bromopropyne comes in contact with copper, high-copper alloys, mercury, or silver.


Flammable, dangerous fire and explosion risk. Irritant.

Health Hazard

3-Bromopropyne is very toxic via the oral route. If inhaled, may be harmful; contact may cause burns to skin and eyes.

Fire Hazard

3-Bromopropyne detonates at 428F or more; ignites by impact. Emits highly toxic fumes of bromides when heated to decomposition. Reacts vigorously with oxidizing materials. Becomes shock-sensitive when mixed with chloropicrin. Unstable, avoid heat, flame, shock, and other chemicals

Safety Profile

A poison by ingestion. A dangerous fire hazard when exposed to heat or flame. The aerated liquid may be ignited by pressure. A dangerous, extremely shock-sensitive explosive. It can detonate when heated to 22O°C, by impact (especially when mixed with chloropicrin), or when heated whde confined. May explode on contact with copper, high copper alloys, mercury, or silver. Mixtures with trichloronitromethane are shockand heat- sensitive explosives. Can react vigorously with oxidizing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of Br-. See also ACETYLENE COMPOUNDS and BROMIDES.
