4-Bromobutyric acid Usage And Synthesis

Chemical Properties	light brown low melting crystals
Uses	4-Bromobutyric acid is used as a bifunctional cross-linker and as a pharmaceutical intermediate. It is also used to synthesize 4-Bromobutyryl chloride.
Synthesis	4-Bromobutyric acid may be produced by a reaction of Y-butyrolactone with hydrogen bromide. The hydrogen bromide to be used may be gas or an aqueous Solution thereof. The reaction temperature is usually about 10 to 100°C., and the amount of hydrogen bromide to be used is usually about 1 to 10 moles per mole of Y-butyrolactone.
