퀴네메라크 화학적 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.
