QUINMERAC C화학적 특성, 용도, 생산
화학적 성질
Crystalline Solid
정의
ChEBI: A quinolinemonocarboxylic acid that is quinoline-8-carboxylic acid carrying additional methyl and chloro substituents at positions 3 and 7 respectively. A residual herbicide used to control broad-leaved weeds on a range of crops including cereals, rape and
beet.
환경귀착
In the field, the DT50 of quinmerac
may range from 3 to 33 days. Losses due to volatilization
are negligible. Soil moisture conditions greatly influence
quinmerac persistence by moderating microbial degradation
and soil leaching. Quinmerac is only slightly adsorbed
to the soil.
신진 대사
Chemical. Quinmerac is stable to heat, light, and in
aqueous solutions with pH values between 3 and 9.
Plant. The degradation and metabolic pathways of
quinmerac have not been extensively studied. In plants,
oxidation of the 3-methyl group to the alcohol and
hydroxylation at the 2-quinoline position are the major
metabolism reactions (56). These quinmerac metabolites
are subsequently conjugated to carbohydrates. The
quantity of quinmerac metabolized varies among species,
ranging from 5% to 80% (56).
Soil. In the soil, degradation of quinmerac was similar
to that observed in plants, resulting in the same
oxygenated and hydroxylated metabolites.
