3-Bromopropionic acid used as quaternization agent in amperometric biosensors. | [Application]
3-Bromopropionic acid is a widely used chemical intermediate. It can be used as a starting material to synthesize derivatives such as esters, acid halides and amides; the active group bromine can undergo a series of reactions, and is mainly used in the fields of pesticides and medicines. Such as the pesticides diflufenacil, furalax and so on. | [Preparation]
3-Bromopropionic acid is prepared by reacting acrylonitrile with hydrogen bromide to obtain bromopropionitrile and then hydrolyzing it. Add acrylonitrile to boiling hydrobromic acid, reflux at 130°C for 6 hours, extract the solid obtained by filtration with ethanol, and obtain the crude product after recovering ethanol by distillation under reduced pressure. By heating 2-cyanoethanol and 40% hydrobromic acid to reflux for 2h, 3-bromopropionic acid can also be produced with a yield of over 80%. | [Synthesis Reference(s)]

The acid crystallises as plates from CCl4. It is soluble in organic solvents and H2O. Its methyl ester has b 65o/18mm and 80o/27mm. The S-benzylisothiouronium salt has m 136o. [Kendall & McKenzie Org Synth Coll Vol I 131 1941, Beilstein 2 IV 764.] |
