Yintoni i-4-Methylumbelliferone CAS 90-33-5?

Iikristale ezimile okwenaliti ze-4-Methylobelliferone. Iqondo lokunyibilika yi-185-186 ℃ (194-195 ℃), iyanyibilika kwi-ethanol, i-acetic acid, izisombululo ze-alkaline, kunye ne-ammonia, iyanyibilika kancinci emanzini ashushu, i-ether, kunye ne-chloroform. I-fluorescence eluhlaza okwesibhakabhaka xa isabela kwi-sulfuric acid exineneyo
