Application

3,5-Difluorobenzylamine (DFBA) has been used as a derivatization reagent in the following studies:
  • Determination of epichlorohydrin (ECH) in water by GC/MS analysis in selected ion monitoring (SIM) mode.
  • Analysis of the epoxides 1,2-epoxybutane, epichlorohydrin, and epifluorohydrin in water by GC/MS analysis.
  • Estimation of ECH in water by on-line solid-phase extraction (SPE) coupled to liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) using a triple quadrupole mass spectrometer.

Trace concentrations of small soluble epoxides are suspected byproducts of drinking water ozonation. However, adequate characterization of epoxide formation is currently limited by the lack of suitable analytical methods to target these chemicals in dilute, but complex aqueous solutions. One
