General description

Lactofen is a broad-spectrum post-emergent herbicide. It acts by inhibiting protoporphyrinogen oxidase by causing lipid peroxidation of the cell membrane.

Application

Lactofen may be used as an analytical reference standard for the determination of the analyte in:
  • Environmental samples by high performance liquid chromatography (HPLC) coupled to tandem mass spectrometric detector (MS/MS), ultraviolet (UV) detector and circular dichroism (CD) detector.
  • Fruit and wheat flour matrices by on-line turbulent flow chromatography (TFC) combined with LC-MS/MS.
  • Agricultural products using gas chromatography coupled to flame photometric detector (GC-FPD).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Lactofen belongs to the diphenylether class of herbicides, which targets protoporphyrinogen oxidase, which in turn causes singlet oxygen generation. In tolerant plants like soybean (Glycine max), the chemical nonetheless causes necrotic patches called "bronzing" in contact areas. Here it is
