| | Isazophos Usage And Synthesis |
| Description | Isazofos is a yellow liquid. Solubility in water is 168 mg/L (20 ?C). It is
miscible with common organic solvents. Log Kow = 2.99.
It is hydrolyzed in aqueous media: DT50 values (20 ?C) at
pH 5, 7, and 9 are 85, 48, and 19 d, respectively. | | Uses | Isazophos is an organophosphate pesticide. | | Uses | Nematocide; turf insecticide. | | Uses | Isazofos is used as a nematicide and soil insecticide in bananas,
citrus, cotton, beet, maize, rice, vegetables, sugar cane and turf. | | Definition | ChEBI: Isazofos is an organic thiophosphate. | | Metabolic pathway | Isazofos is metabolised in soil to its hydrolysis product 5-chloro-1-
isopropyl-3-triazolol. The oxon metabolite has apparently not been
identified. | | Metabolism | In mammals, administered isazofos is
rapidly metabolized and excreted, primarily in the urine,
without accumulation in the body. The degradation route
of isazofos in soil is primarily the hydrolysis mediated
by microorganisms to give 5-chloro-1-isopropyl-3-triazole.
The half-life in soils is about 10 d. | | Toxicity evaluation | Acute oral LD50 for rats is
40–60 mg/kg. Inhalation LC50 (4 h) for rats is about
0.24 mg/L air. NOEL (90 d) for rats is 2 mg/kg diet
(0.1 mg/kg/d). | | Degradation | Isazofos is hydrolysed more rapidly in alkaline rather than acid solution.
The DT50 values at pH 5, 7 and 9 were 85, 48 and 19 days, respectively
(PM). |
