Application

2-Bromoethylamine hydrobromide (BEA-HBr) can be used as a reactant in the preparation of:
  • Amino-functionalized ionic liquid, 1-aminoethyl-3-methylimidazolium hexafluorophosphate ([2-aemim][PF6]). [2-aemim][PF6] is employed as a catalyst in the synthesis of 4H-pyrans derivatives by treating with aromatic aldehydes, malononitrile, ethyl acetoacetate via Knoevenagel condensation reaction.
  • 2-(N-aryl-N-aroyl)amino-4,5-dihydrothiazole derivatives via cyclocondensation reaction.

It can be also employed as an alkylating agent for the surface modification of nylon to obtain primary/secondary/tertiary amine groups.
