HEPTENOPHOS Usage And Synthesis
DescriptionHeptenophos is a light brown liquid or crystalline mass. It is soluble in water (2.2 g/L at 20 ?C) and miscible with most organic solvents, except aliphatic hydrocarbons. Log Kow = 2.32. Heptenophos is hydrolyzed in acidic and alkaline media.
Chemical PropertiesPale amber liquid; miscible in most organic solvents; soluble in xylene, acetone, and methanol.
UsesHeptenophos is used to control sucking pests (primarily aphids) in a wide range of crops. It is also used as an ectoparasiticide to control ticks, lice, mites and fleas in farm animals and pets.
UsesInsecticide.
UsesHeptenophos is a pesticide used for fruits and vegetables.
DefinitionA nonpersistent contact and systematic phosphate insecticide.
HazardPoison; moderately toxic.
Metabolic pathwayMetabolism of heptenophos in soils is by hydrolysis to 7-chloro-bicyclo[3.2.0]hept-2-en-6-one, further transformations of which involve microbially-mediated Baeyer-Villiger oxidations of the cyclobutanone moiety, ring opening of the resultant lactones, dechlorination and dehydrochlorination followed by ultimate mineralisation to CO2 and conversion to unextractable soil-bound residues. In rats, 7-chlorobicyclo[3.2.0]hept-2-en-6-one is further transformed to give the Favorskiirearranged product bicyclo[3.l.0]hex-2-en-6-exo-carboxylic acid as a urinary metabolite.
MetabolismIn rats 90% of heptenophos is excreted in the urine and 6% in the feces as water-soluble metabolites within 6 days after oral administration. In plant (lettuce), it is completely transformed to watersoluble metabolites without accumulation within 4 d. In soil, it is rapidly degraded bymicroorganisms, DT50 (20 ?C) being less than 4 h.
Toxicity evaluationAcute oral LD50 for rats is 96–121 mg/kg. Inhalation LC50 (4 h) for rats is 0.95 mg/L air. NOEL (2 yr) for rats is 15 mg/kg diet (0.75 mg/kg/d). ADI is 3 μg/kg b.w.
DegradationHeptenophos is hydrolysed in acidic and alkaline media (PM).
