TimoropetariniKo te ingoa pūtaiao o te rongoā ko "3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide", he matū matū waro. Ko te tātai matū ko C28H30O4, ā, ko te taumaha ngota he 430.54. He paura tioata mā. He ngāwari te wairewa i roto i te ether, te acetone, te waikawa whanariki me ngā otinga kawakore, ā, kāore e wairewa i roto i te wai. He maha ngā wā e whakamahia ana hei tohu waikawa-pūtake, ā, ko tōna awhe huringa tae pH he 9.4-10.6, ā, ka huri te tae mai i te kore tae ki te kikorangi. Ina whakamahia, he maha ngā wā ka whakaritea hei otinga 0.1% 90% etanoru. He maha hoki ngā wā ka whakaritea me ētahi atu tohu hei hanga i tētahi tohu whakakotahi ngawari kia whaiti ake ai tōna awhe huringa tae, kia mārama ake ai te tirohanga.

He maha ngā wā ka whakamahia te Thymolphthalein hei tohu waikawa-pūtake, me te awhe huringa tae pH o te 9.4 ki te 10.6, me te huringa tae mai i te kore tae ki te kikorangi. Ina whakamahia, he maha ngā wā ka whakaritea hei otinga 0.1% 90% etanoru, ā, he maha ngā wā ka konatunatua ki ētahi atu tohu hei hanga i tētahi tohu whakauru kia whaiti ake ai, kia mārama ake ai hoki te awhe huringa tae ki te mātakitaki. Hei tauira, ko te tohu i hangaia mā te whakaranu i tētahi otinga 0.1% etanoru o tēnei matū me tētahi otinga 0.1% etanoru o te phenolphthalein he kore tae i roto i tētahi otinga waikawa, he papura i roto i tētahi otinga kawakore, ā, he rōhi i te pH 9.9 (te pūwāhi huringa tae), he tino ngāwari ki te mātakitaki.
