Description

General description

Lactofen is a broad-spectrum post-emergent herbicide. It acts by inhibiting protoporphyrinogen oxidase by causing lipid peroxidation of the cell membrane.[1]

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[2] 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.
