Documented Uses

• 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.
