Kodi O-Cresolphthalein CAS 596-27-0 ndi chiyani?

O-cresol phthalein ndi ufa wa kristalo woyera mpaka wachikasu wopepuka. Malo osungunuka 216 ~ 217℃. Amasungunuka mu mowa, ether ndi glacial acetic acid, amasungunuka pang'ono m'madzi, samasungunuka mu benzene, amasungunuka mu alkali wosungunuka. Amagwiritsidwa ntchito ngati chizindikiro cha acid-base mu chemistry yowunikira. Ali ndi kapangidwe ka mankhwala kofanana ndi ka phenolphthalein, ndipo mtundu wake umasinthasintha ndi 8.2 (wopanda utoto) -9.8 (wofiira) (mtundu wa Phenolphthalein umasinthasintha ndi 8.2-10). Kapangidwe ka asidi ndi kopanda utoto wa lactone, ndipo maziko ake ndi a quinone ndipo amawoneka ofiira.
