1. Amagwiritsidwa ntchito ngati chizindikiro cha acid-base komanso chizindikiro chodziwira mtengo wa asidi wamafuta
Phenolphthalein ili ndi chidwi chosintha mitundu. Pansi pa asidi-pafupi ndi ndale (pH0-8.2), mamolekyu a phenolphthalein samalekanitsa ndipo alibe mtundu. M'malo amchere (pH8.2-12), gulu la phenol hydroxyl limagawidwa kukhala quinone, ndipo chomangira cha lactone chasweka, atomu ya kaboni mkatikati mwa maselo amasintha kuchoka ku sp3 hybridization kupita ku sp2 hybridization, maatomu onse a carbon ali mu ndege imodzi, chilengezo chonse chophatikizidwa ndi molekyulu chimapanga chomangira cha 19-center 19-electron lalikulu π, ndipo ma elekitironi aulere m'dongosololi amatha kuyamwa mafunde amtundu wa electromagnetic. Amatulutsa pinki-burgundy. M'malo amphamvu asidi, phenolphthalein molekyulu ndi protonated kwambiri, ndipo chomangira cha lactone chimasweka, kupanga chomangira chachikulu π ndi 19 centers ndi 18 ma elekitironi, chomwe chili chofiira chalalanje. Katundu wa phenolphthalein nthawi zambiri amagwiritsidwa ntchito pozindikira asidi ndi maziko.
Chifukwa phenolphthalein ali ndi mafuta solubility, ndizoyenera makamaka ngati chizindikiro cha titration yopanda madzi, monga chizindikiro cha kutsimikiza kwa acidity mu mafuta.
2. Amagwiritsidwa ntchito ngati mankhwala ofewetsa thukuta
Phenolphthalein imapanga sodium yosungunuka m'malo amchere am'matumbo, imayambitsa mitsempha ya plexus mu khoma la matumbo, mwachindunji amachita pa matumbo yosalala minofu, ndipo kumawonjezera matumbo peristalsis. Nthawi yomweyo, phenolphthalein imalepheretsanso kuyamwa kwa madzi m'matumbo, kotero kuti madzi ndi electrolyte zimawunjikana m'matumbo, kubweretsa mankhwala ofewetsa tuvi tolimba.
The mankhwala ofewetsa tuvi tolimba zotsatira phenolphthalein zimadalira alkalinity wa m`mimba madzimadzi. M'mikhalidwe yabwino, zotsatira zake ndi wofatsa ndipo kawirikawiri zimayambitsa kuphipha m'mimba. Choncho, ndizoyenera chizolowezi chodzimbidwa, kapena kuyeretsa matumbo panthawi ya colon ndi rectal endoscopy ndi X-ray. Pali mapiritsi, suppositories ndi mitundu ina ya mlingo.
Kutenga phenolphthalein m'mimba chimbudzi, kuchepetsa mayamwidwe a chakudya, kotero pali zotsatira zinazake zowonda, koma ngati atatengedwa kwa nthawi yayitali, zidzayambitsa kusokonezeka kwamadzimadzi ndi electrolyte chifukwa cha kutsekula m'mimba kwambiri, kuwononga zakudya za anthu, kuwononga m'mimba mantha dongosolo.
Pa October 27, 2017, Bungwe la World Health Organisation for Research on Cancer linaphatikiza phenolphthalein pamndandanda wamagulu amagulu a 2B.
