Application

Methyl 11-bromoundecanoate can be used as a reactant to synthesize:
  • Methyl 11-(2,5-dibromophenoxy)undecanoate, which is employed as a precursor to prepare acetylenic cyclophanes.
  • Methyl 11-[(1-phenyl-1H-tetrazol-5-yl)thio]undecanoate, a key intermediate applicable in the synthesis of emmyguyacins side chain.
  • Betain derivatives of 11-bromoundecanoic acid, as potential microbial agents.
