Definition
ChEBI: An aminopyridine that is pyridin-4-amine substituted by chloro groups at positions 3 and 5, a fluoro group at position 6 and a carboxymethoxy group at position 2.

mögliche Exposition
Those who manufacture, distribute or use this pyridinecarboxylic acid/pyridine herbicide.
Environmental Fate
The DT₅₀ in soil is relatively short, ranging from 5 to 9 days in experiments conducted in the laboratory. This rapid degradation is due to microbes.Because of its rapid soil degradation, little fluroxypyr is available for other dissipation processes, e.g., leaching.
Stoffwechsel
Fluroxypyr is stable under acidic conditions and moderately stable in alkaline conditions; e.g., the DT₅₀ in water at pH 9 is 185 days. Degradation occurs at temperatures above its melting point. Fluroxypyr is stable in light.
Plant. The metabolism of fluroxypyr has not been fully described. Conjugates of fluroxypyr have been observed in tolerant plants.
Soil. Fluroxypyr is rapidly metabolized by soil microbes via the removal of the carboxyl group or acetic acid group, yielding 4-amino-3,5-dichloro-6-fluoro- 2-methoxypyridine, and 4-amino-3,5-dichloro-6-fluoro-2- pyridinol, respectively.
Versand/Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.
Toxicity evaluation
Mammalian Toxicity. Fluroxypyr appears to be rapidly excreted, unmodified, in the urine of animals. The acute oral LD₅₀ for rat is 2405 mg/kg.
Weed Resistance/Modified Crop Tolerance. Fuerst et al. (48) reported fluroxypyr resistance in yellow starthistle (Centaurea solstitialis). No crops with modified tolerance toward fluroxypyr are currently in production.
Inkompatibilitäten
May not be compatible with nitrates. Moisture may cause hydrolysis or other forms of decompo sition; forming a strong acid. Temperatures above 250℃ can cause decomposition. Methyl ester: Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is suffi ciently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solu tions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Waste disposal
Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an after burner and scrubber. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesti cide containers.
