METHACRIFOS Chemical Properties,Usage,Production

Uses

Grain protectant, insecticide, acaricide.

Uses

trans-Methacrifos is used as a pesticide used to protect crops and vegetation.

Definition

ChEBI: Methacrifos is an organic thiophosphate.

Metabolism

Methacrifos administered in animals is rapidly metabolized and excreted. The carboxy methyl ester bond is cleaved as well as the phosphoryl methyl and vinyl ester bonds. Oxidative desulfuration also occurs.

Toxicity evaluation

The acute oral LD₅₀ for rats is 678 mg/kg. Inhalation LC50 (4 h) for rats is 2.2 mg/L air. NOEL (2 yr) for rats is 0.6 mg/kg b.w. daily. ADI is 6 μg/kg b.w.
