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

I-O-cresol phthalein yipowder yekristale emhlophe ukuya kwephuzi ekhanyayo. Iqondo lokunyibilika 216 ~ 217℃. Inyibilika kwi-alcohol, ether kunye ne-glacial acetic acid, inyibilika kancinci emanzini, ayinyibiliki kwi-benzene, inyibilika kwi-dilute alkali. Isetyenziswa njengesalathisi se-acid-base kwi-analytical chemistry. Inesakhiwo seekhemikhali esifanayo kunye neempawu zomzimba nezekhemikhali kwi-phenolphthalein, kwaye uluhlu lwayo lokutshintsha kombala yi-8.2 (engenambala)-9.8 (ebomvu) (uluhlu lokutshintsha kombala lwePhenolphthalein yi-8.2-10). Ulwakhiwo lwayo lwe-asidi luyimo ye-lactone engenambala, kwaye isakhiwo sayo sesiseko siyimo ye-quinone kwaye sibonakala sibomvu.
