In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Aquatic dissipation of the herbicide triclopyr in Lake Minnetonka, Minnesota, published in 2000-05-31, which mentions a compound: 1970-40-7, Name is 2,3,5-Trichloropyridin-4-ol, Molecular C5H2Cl3NO, Related Products of 1970-40-7.
A study of the aquatic fate of the triethylamine salt of triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) was conducted in three bays of Lake Minnetonka, Minnesota. Triclopyr is under review by the US Environmental Protection Agency as a selective aquatic herbicide. The primary purpose of this study was to determine dissipation rates of the parent active ingredient, triclopyr, and its major metabolites, 3,5,6-trichloropyridinol (TCP) and 3,5,6-trichloro-2-methoxypyridine (TMP) in selected matrixes, including water, sediment, plants, finfish, and shellfish. Two 6.5-ha plots dominated by the weedy species Eurasian watermilfoil (Myriophyllum spicatum L) were treated with triclopyr-triethylammonum at a rate of 2.5 mg AE/L (2.5 ppm) on June 21-23, 1994. A third 6.5-ha plot was established as an untreated reference Water and sediment samples were collected from within the plots and at selected locations up to 1600 m outside of the plots through six weeks’ post-treatment for chem. residue anal. In addition, residue samples were collected from the target and nontarget plants and other nontarget matrixes, including game and rough fish, clams and crayfish. All test animals were sequestered in cages located in the center of each plot, and samples were collected through four weeks’ post-treatment. Half-lives for dissipation of triclopyr and TCP in water ranged from 3.7 to 4.7 days and from 4.2 to 7.9 days, resp., with trace amounts of TMP found. Peak triclopyr sediment values ranged from 257 to 335 ng/g, with a mean half-life of 5.4 days, while peak TCP sediment levels ranged from 27 to 65 ng/g (mean half-life = 11.0 days). Trace levels of TMP were detected at one treatment site at one sampling event. Triclopyr and TCP accumulated and cleared from animal tissues proportionately to concentrations in the water (triclopyr dissipation half-lives <11 days, TCP <14 days). TMP levels were two to three times higher than those of the other compounds, particularly in visceral tissue. In all cases, residues of these compounds were higher in the inedible portions of the animals, and were usually higher in bottom-feeding fish species. I hope my short article helps more people learn about this compound(2,3,5-Trichloropyridin-4-ol)Related Products of 1970-40-7. Apart from the compound(1970-40-7), you can read my other articles to know other related compounds.
