Abstract: A convenient synthetic route of deuterium-labeled D5-cyhalothrin, D5-fenpropathrin, and
D5-fenvalerate is described with 98.7%, 98.5%, and 98.3% isotopic enrichment and high chemical purities
using D6-phenol as labeled starting material. These structures and isotope-abundance were confirmed
by 1H NMR and mass spectrometry. The prepared D5-cyhalothrin, D5-fenpropathrin, and D5-
fenvalerate can be used as a standard internal reagent for the determination of residual pyrethroids of
food and environment.
