Phenolphthalein yog cov organic acid uas tsis muaj zog, uas zoo nkaus li dawb los yog daj me ntsis zoo crystals ntawm chav tsev kub. Nws yog odorless thiab tasteless. Nws yog qhov nyuaj rau yaj hauv dej tab sis yooj yim soluble hauv cawv (ethanol) thiab ether. Nws yog yaj nyob rau hauv dej cawv tov los ua ib tug acid-base qhia. Nws tsis muaj xim nyob rau hauv acidic tov thiab liab nyob rau hauv alkali tov los yog alkali hlau carbonate tov. Txawm li cas los xij, yog tias nws yog nyob rau hauv cov ntsiab lus alkali, nws yuav tsim cov xim tsis muaj xim trimetallic acid. ntsev, xim liab ploj mus

1. Pharmaceutical raw cov ntaub ntawv rau kev lag luam kws tshuaj: haum rau cov cwj pwm tsis zoo thiab tawv ncauj cem quav, muaj nyob rau hauv cov ntsiav tshuaj, suppositories thiab lwm yam tshuaj.
2. Phenolphthalein siv nyob rau hauv cov organic synthesis: feem ntau yog siv rau hluavtaws plastics, tshwj xeeb tshaj yog rau cov synthesis ntawm naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Hom polymer no muaj kev tiv thaiv zoo heev, tiv thaiv dej, thiab tshuaj tiv thaiv. Vim nws cov corrosion kuj, kub aging kuj thiab zoo ua thiab formability, fibers, coatings thiab composite cov ntaub ntawv uas ua los ntawm nws yog dav siv nyob rau hauv cov khoom siv hluav taws xob, mechanical khoom, tsheb thauj mus los, aerospace, atomic zog engineering thiab tub rog teb.
3. Phenolphthalein siv los ua acid-base indicator, indicator for titration of non-aqueous solutions, and reagent for chromatographic analysis.
