Description and Uses

Cyclosulfamuron is a cereal and rice herbicide. It has a low aqueous solubility, is volatile and, based on its chemical properties, is only slightly mobile and would not be expected to leach to groundwater. It is not generally persistent in soil systems. It has a low mammalian toxicity and has a high potential to bioaccumulate. It is moderately toxic to most aquatic species, birds, honeybees and earthworms.

Cyclosulfamuron can be used in analytical study of importance of optimizing chromatographic conditions and mass spectrometric parameters for supercritical fluid chromatography/mass spectrometry.
