Pyraflufen-ethyl(CAS: 129630-19-9)

Pyraflufen-ethyl is a crystalline compound with a molecular weight of approximately 257.26 g/mol. It has a low water solubility and is relatively stable under normal conditions. It reacts selectively with certain functional groups and is known for its herbicidal activity.

Pyraflufen-ethyl is typically synthesized via a multi-step process involving the condensation of 5-chloro-2-methyl-4-nitrophenol and ethyl 2-(trifluoromethyl)pyridine-3-carboxylate. The reaction is usually catalyzed by a transition metal and yields a high percentage of the desired product, with good selectivity and yield.

Pyraflufen-ethyl is primarily used in the agricultural industry as a herbicide. It is also studied for its potential applications in pharmaceuticals and environmental science, particularly in selective weed control in crops.

When handling Pyraflufen-ethyl, protective equipment such as gloves, safety glasses, and a respirator should be worn. It should be stored in a cool, dry place away from direct sunlight. In case of spill, ensure proper ventilation and use appropriate containment to prevent environmental release. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines.
