应用领域3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) is not known to be produced commercially except for research purposes、Disinfection byproducts are formed when disinfectants used in water treatment plants react with bromide and/or natural organic matter (i.e、decaying vegetation) present in the source water. /Disinfection byproducts/、A project to isolate and identify the mutagenic components formed in pulp chlorination was initiated in 1979 at the Pulp and Paper Research Institute of Canada. Mutagenicity of the concentrates and fractions from the pulp chlorination process were tested for reverse mutations in Salmonella typhimurium strain TA100. Most of the mutagenicity was consistently found in one fraction、suggesting one primary mutagen. Because analytical techniques were not sufficiently advanced to easily identify the compound、the compound was called "Mutagen X" or "MX" After about a year of additional work

数据库记载的用途

  • 3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) is not known to be produced commercially except for research purposes.
  • Disinfection byproducts are formed when disinfectants used in water treatment plants react with bromide and/or natural organic matter (i.e., decaying vegetation) present in the source water. /Disinfection byproducts/
  • In acidic solutions MX is a furanone, but at physiological pH it exists primarily in a ring-open form, namely Z-2-chloro-3-(dichloromethyl)-4-oxo-butenoic acid (z-MX), a fraction of which undergoes isomerization to its geometric isomer (E)-2-chloro-3-(dichloromethyl)-4-oxobutenoic acid (EMX).
  • Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
  • Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.
  • In another experiment, a dose of 2 mg/kg (14C)MX was administered to Wistar rats and radioactivity was determined in tissues after 2 and 6 hr. After 2 hr, the highest amount of radioactivity was detected in kidneys, followed by the stomach, ileum, urinary bladder and liver. At 6 hr, the concentration of radioactivity was markedly decreased in kidneys and urinary bladder and to a lesser extent in the gastrointestinal tract.
