ThymolphthaleinO le igoa faasaienisi o le “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, o se reagent organic. Ole fua ole vaila'au ole C28H30O4, ma ole mamafa ole mole ole 430.54. O se pauta tioata pa'epa'e. E faigofie ona solu i le ether, acetone, sulfuric acid ma vaifofo alkaline, ma e le mafai ona solu i le vai. E masani ona faʻaaogaina e avea o se faʻamaoniga o le acid-base, ma o lona pH suiga lanu lanu o le 9.4-10.6, ma o le lanu e sui mai le lanu i le lanumoana. A fa'aaogaina, e masani ona saunia i se vaifofo ethanol 0.1% 90%. E masani fo'i ona saunia ma isi fa'ailoga e fai ai se fa'ailo tu'ufa'atasi mālū ina ia vaapiapi le va'aiga o suiga lanu ma manino atili ai le mata'ituina.

O le Thymolphthalein e masani ona faʻaaogaina e fai ma faʻamaoniga o le acid-base, faʻatasi ai ma le suiga o le lanu o le pH o le 9.4 i le 10.6, ma se suiga lanu mai le leai se lanu i le lanumoana. Pe a faʻaaogaina, e masani ona saunia e pei o se vaifofo ethanol 0.1% 90%, ma e masani ona faʻafefiloi ma isi faʻailoga e fai ai se faʻailoga fefiloi ina ia vaapiapi ma manino le vaʻaiga o lona lanu e matau. Mo se faʻataʻitaʻiga, o se faʻailoga na faia e ala i le faʻafefiloi o le 0.1% ethanol solution o lenei reagent ma le 0.1% ethanol solution o le phenolphthalein e leai se lanu i se vaifofo acidic, lanu viole i se vaifofo alkaline, ma tulaʻi i le pH 9.9 (tulaga suiga lanu), e matua faigofie lava ona matauina.
