Kuyini i-5,5-Dimethylhydantoin CAS 77-71-4?

I-5,5-Dimethylhydantoin iyikristalu elimhlophe eliyi-prismatic noma i-crystalline powder. Iphuzu lokuncibilika lingu-175 ℃. Incibilika emanzini, i-hexanol, i-ethyl acetate, kanye ne-dimethyl ether, incibilika kancane ku-isopropanol, i-acetone, kanye ne-methyl ethyl ketone, ayincibiliki kuma-hydrocarbon anamafutha kanye ne-trichloroethylene. Ayinaphunga, iyakwazi ukwehlisa i-acidity, futhi ine-acidic.
