Abstract

What is described is a thermodynamically stable crystal modification of the herbidically active compound 2-({2-chloro-4-(methylsulfonyl)-3-[(2,2,2-trifluoroethoxy)methyl]phenyl}carbonyl)cyclohexan-1,3-dione (tembotrione). This thermodynamically stable crystal modification has particular advantages in the stability of suspension formulations.
