Test solutions
- Details on test solutions:
- Identity and concentration of auxiliary solvent for dispersal: Agent has limited water solubility (0.1%). Stock solutions
of agent were prepared at 500 mg/ml in dimethylformamide
(DMF). Stock solution was diluted in DMF to prepare
solutions at 0.300, 0.180, 0.108, and 0.065 g/ml. These
were further diluted with well water to prepare final media.
