ThymolphthaleinZita resainzi “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, inova organic reagent. Iyo kemikari formula ndeye C28H30O4, uye molecular uremu ndeye 430.54. Icho chichena checrystalline powder. Inonyungudika nyore nyore muether, acetone, sulfuric acid uye alkaline mhinduro, uye isinganyungudika mumvura. Inowanzo shandiswa senge acid-base chiratidzo, uye pH yayo shanduko yeruvara renji ndeye 9.4-10.6, uye ruvara rwunoshanduka kubva rusina ruvara kuenda rwebhuruu. Kana yashandiswa, inowanzogadzirirwa kuita 0.1% 90% ethanol solution. Iyo inowanzo gadzirirwa pamwe nezvimwe zviratidzo kuti igadzire zvinyoro zvakasanganiswa chiratidzo kuti iite kuti shanduko yeruvara iite diki uye kucherekedza kujeka.

Thymolphthaleininowanzoshandiswa sechiratidzo cheacid-base, ine pH shanduko yeruvara kubva pa9.4 kusvika 10.6, uye shanduko yeruvara kubva isina ruvara kuenda kublue. Kana yakashandiswa, inowanzogadzirirwa se 0.1% 90% ethanol solution, uye inowanzosanganiswa nezvimwe zviratidzo kuti iite chiratidzo chakavhenganiswa kuita kuti ruvara rwayo rwekuchinja ruve rwakatetepa uye rwakajeka kutarisa. Semuenzaniso, chiratidzo chakaitwa nekusanganisa 0.1% ethanol solution yeiyi reagent ine 0.1% ethanol solution ye phenolphthalein haina ruvara muine acidic solution, yepepuru mualkaline solution, uye yakasimuka papH 9.9 (color change point), zviri nyore kuona.
