Appearance:1,3-dichloro-5,5-dimethylhydantoin is a white powder with a weak chlorine odor. Conflagrates at 414°F (turns brown). Chlorine gas evolves at temperatures > 410°F. (NTP, 1992)
Density:1.5 g/cm3 @ Temp: 20 °C
Melting Point:132 °C
Boiling Point:212° (sublimes)
Flash Point:346°F
Refractive Index:1.5720 (estimate)
Water Solubility:water: soluble 0.21% at 25°C(lit.)
Storage Conditions:Safe Storage of Pesticides. Always store pesticides in their original containers, complete with labels that list ingredients, directions for use, and first aid steps in case of accidental poisoning. Never store pesticides in cabinets with or near food, animal feed, or medical supplies. Do not store pesticides in places where flooding is possible or in places where they might spill or leak into wells, drains, ground water, or surface water.
