General description

Pyrasulfotole, a 4-hydroxyphenylpyruvate dioxygenase inhibitor, is well-known for its role in weed control, as well as excellent crop selectivity.

Application

Pyrasulfotole may be used as an analytical reference standard for the determination of the analyte in:
  • Agricultural products by liquid chromatography-time of flight mass spectrometry (LC-TOF-MS).
  • Vegetables and fruits by LC coupled to tandem mass spectrometry (MS/MS).

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