Applications A thiol reactive fluorescent probe for the labelling of proteins. Rhodamine dyes are used extensively in various aspects of fluorescence microscopy because of their brightness and resistance to photobleaching. They are valuable in studies directed at probing changes in orientation and mobility of proteins using fluorescence anisotropy measurements. It is a mixture of the 6-Iodo and 6-chloro.

Applications Deschloro-2-phenylthio-thiamethoxam is an impurity of thiamethoxam (T344180), which is a neonicotinoid insecticide. Reports show that when exposed to neonicotinid pesticides honeybees have probelms returnign home after foraging and bumblebee colonies grow poorly and produce fewer queens.
