Application of coupled liquid chromatography-mass spectrometry in photolysis studies of the herbicide triflusulfuron-methyl.
Pest Manag Sci. 2001 Jun; 57(6):527-30.PM

Abstract

The photochemical fate of the herbicide triflusulfuron-methyl in aqueous solution under UV light (lambda > 290 nm) was investigated. Nine photoproducts were detected and tentatively identified by LC/MS and LC/MS/MS analysis. The main routes of degradation involve the cleavage and/or contraction of the sulfonylurea bridge with the elimination of sulfur dioxide, which increases the acidity of the reaction medium. On the basis of the results obtained a photodegradation pathway is proposed.
