Product Name:1-Bromobut-3-en-2-one
English Name:1-Bromobut-3-en-2-one
CAS No.:155622-69-8
Aliases:1-Bromo-3-buten-2-one, Bromomethyl vinyl ketone, 3-Buten-2-one, 1-bromo-
Molecular Formula:C4H5BrO
Physical Properties:Light yellow to brown liquid with a pungent odor, sensitive to light and heat. Density approximately 1.55 g/cm³ at 20°C, boiling point approximately 135°C (literature value, may be accompanied by decomposition), flash point above 60°C. Slightly soluble in water; soluble in ethanol, diethyl ether, acetone and other organic solvents. Exhibits dual reactivity of α-bromoketone and enone; requires storage in a cool, dark, sealed environment.
Uses:Used as an organic synthesis intermediate, combining the electrophilicity of α-bromoketones with the Michael acceptor activity of enones, commonly employed for constructing C-C and C-N bonds. It is also used in the synthesis of heterocyclic compounds such as pyrazoles, thiazoles and oxazoles, as well as in the preparation of pharmaceutical intermediates, fine chemicals and polymer crosslinking agents.
