Flurprimidol Chemical Properties,Uses,Production
Description
Flurprimidol is a plant growth regulator used to retard growth in a wide range of mono- and dicotyledonous weed species. It is moderately soluble in water, has a low volatility but there is some risk of drift under certain conditions. Generally, it is not persistent in soils or water-sediment systems. Regarding human health there is some concern that it may be a reproduction/developmental toxin. Oral mammalian toxicity is moderate. Toxicity to biodiversity is low to moderate.
Chemical Properties
White to pale yellow or buff crystalline solid. Slight aromatic odor.
Uses
Flurprimidol is a plant growth regulator used to control stem elongation.
Uses
Growth retardant for grasses.
Production Methods
Flurprimidol is commercially produced through a streamlined synthesis of 5-substituted pyrimidines, optimised for efficiency and reduced environmental impact. Traditionally, this process required cryogenic conditions and extended reaction times. However, an improved commercial method has been developed that bypasses the need for low temperatures and significantly shortens the synthesis duration; from four days to just one. This modern approach involves the condensation of appropriate aldehydes and amidines to form the pyrimidine ring, followed by selective substitution with a fluorinated phenyl group and an alcohol moiety.
Definition
ChEBI: Flurprimidol is an alkylbenzene.
Mechanism of action
Absorbed by leaves and roots. Gibberellin biosynthesis inhibitor.
Potential Exposure
Pyrimidine plant growth regulator Used on turf and ornamental trees which reduces internode and leaf elongation in cool and warm seasons. A turf grass growth deterrent.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.
Incompatibilities
Decomposes in temperatures above 200℃. May react with strong oxidizers such as chlorates, peroxides, nitrates, etc.
Waste Disposal
Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by con tacting your regional EPA office. If this material cannot be disposed of according to label instructions, it may be dis solved or mixed with a combustible solvent and burned in a chemical incinerator equipped with an afterburner and scrubber. In accordance with 40CFR165, follow recommen dations for the disposal of pesticides and pesticide contain ers. Noncombustible containers should be crushed and buried under more than 40 cm of soil.
Pesticide Type
Plant Growth Regulator; Herbicide
