Niki O-Cresolphthalein CAS 596-27-0?

O-cresol phthalein ni ifu yera kandi yoroheje yumuhondo wa kristaline. Gushonga ingingo 216 ~ 217 ℃. Gushonga muri alcool, ether na acide acetike ya glacial, gushonga gake mumazi, kudashonga muri benzene, gushonga muri alkali. Ikoreshwa nkibipimo bya aside-shingiro muri chimie yisesengura. Ifite imiterere isa na chimique nibintu bya fiziki na chimique na fenolphthalein, kandi ibara ryayo rihindura ibara ni 8.2 (ibara ritagira ibara) -9.8 (umutuku) (Ibara rya Phenolphthalein ni 8.2-10). Imiterere ya acide nuburyo bwa lactone idafite ibara, kandi imiterere yibanze ni form ya quinone kandi igaragara nkumutuku.
