Fluridone is a selective herbicide used primarily to control aquatic and terrestrial weeds, particularly in rice paddies and non-crop areas. It inhibits carotenoid biosynthesis, leading to bleaching and plant death. This chemical has a CAS number of 59756-60-4, with the molecular formula C19H14F3NO and a molecular weight of 329.32. It should be stored at ambient temperatures and handled with caution, as it carries a "Danger" signal word. Molekula supplies Fluridone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
