에트림포스 C화학적 특성, 용도, 생산
개요
Etrimfos is a colorless liquid, mp ?3.35 ?C, vp 6.5 mPa
(20 ?C). Solubility in water is 40 mg/L (23–24 ?C). It is
miscible with most organic solvents. Log Kow > 3.3. Neat
etrimfos is unstable and degrades ca. 40% in 28 d at
50 ?C, but the dilute solutions in nonpolar solvents and its
formulations are stable (about 5% loss in 1 y at ca. 20 ?C).
It is hydrolyzed in aqueous media; DT50 (25 ?C) at pH 3, 6,
and 9 are 0.4, 16, and 14 d, respectively.
용도
Etrimfos is used to control chewing insects in top fruit, vines,
olives and a number of other crops. It is also used to control stem borers in
rice and insect and acarid pests of stored products.
위험도
Toxic.
신진 대사 경로
Etrimfos is principally degraded in soil and plants via dearylation of
etrimfos itself or by hydrolysis of etrimfos oxon to the pyrimidinol
(6-ethoxy-4-hydroxy-2-ethylpyrimidine), further metabolism of which
involves de-ethylation to a dihydroxypyrimidine (2-ethyl-4,6-dihydroxypyrimidine).
In mammals both hydrolysis and demethylation to desmethyl
etrimfos are involved in detoxification. Additionally, the ethyl and
ethoxy groups of the pyrimidinol hydrolysis product may be hydroxylated
and conjugated. Etrimfos oxon is metabolically highly unstable and
is often not detected.
