ThymolphthaleinʻO ka inoa ʻepekema ʻo “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, ʻo ia ka mea hoʻoponopono kūlohelohe. ʻO C28H30O4 ka paona kemika, a ʻo ke kaumaha molekala he 430.54. He pauda kristal keʻokeʻo. Hiki ke maʻalahi i ka ether, acetone, sulfuric acid a me ka alkaline solutions, a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. Hoʻohana pinepine ʻia ia ma ke ʻano he hōʻailona acid-base, a ʻo kona ʻano pH hoʻololi kala ʻo 9.4-10.6, a hoʻololi ke kala mai ka kala ʻole i ka uliuli. Ke hoʻohana ʻia, hoʻomākaukau pinepine ʻia i loko o kahi solution 0.1% 90% ethanol. Hoʻomākaukau pinepine ʻia me nā mea hōʻailona ʻē aʻe e hana i kahi hōʻailona hui ʻoluʻolu e hōʻemi i ka laulā hoʻololi kala a ʻoi aku ka maopopo o ka nānā ʻana.
