Iyini i-O-Cresolphthalein CAS 596-27-0?

I-O-cresol phthalein iyimpuphu yekristalu emhlophe kuya kophuzi okhanyayo. Iphuzu lokuncibilika 216 ~ 217℃. Incibilika ku-alcohol, ether kanye ne-glacial acetic acid, incibilika kancane emanzini, ayincibiliki ku-benzene, incibilika ku-alkali encibilikisiwe. Isetshenziswa njengesibonakaliso sesisekelo se-acid kumakhemikhali okuhlaziya. Inesakhiwo samakhemikhali esifanayo kanye nezakhiwo zomzimba nezamakhemikhali njenge-phenolphthalein, futhi ububanzi bayo bokushintsha kombala bungu-8.2 (awunambala)-9.8 (obomvu) (ububanzi bokushintsha kombala be-Phenolphthalein bungu-8.2-10). Isakhiwo sayo se-acid singesimo se-lactone esingenambala, kanti isakhiwo sayo sesisekelo singesimo se-quinone futhi sibonakala sibomvu.

Isicelo

I-O-Cresolphthalein isetshenziswa njengesibonakaliso sesisekelo se-asidi esinobubanzi bokushintsha kombala obuqala ku-pH8.2 (okungenambala) kuya ku-9.8 (obomvu).
