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

Amakristalu angu-4 amise okwenaliti ye-Methylobelliferone. Iphuzu lokuncibilika 185-186 ℃ (194-195 ℃), ancibilika ku-ethanol, i-acetic acid, izixazululo ze-alkaline, kanye ne-ammonia, ancibilika kancane emanzini ashisayo, i-ether, kanye ne-chloroform. I-fluorescence eluhlaza okwesibhakabhaka uma isabela ku-sulfuric acid egxilile
