Phenolphthalein ayaa ugu horrayn loo adeegsadaa tilmaame ahaan titrations-saldhigga aashitada, halkaas oo ay ku muujiso isbeddel midab la'aan ah oo casaan ah maaddaama pH ay ka beddesho acidic una beddesho alkaline.Dabeecaddani waxay ka dhigaysa mid qiimo leh shaybaarada waxbarashada iyo goobaha cilmi-baarista ee kala duwan, iyadoo hubinaysa go'aaminta dhamaadka saxda ah.
Intaa waxaa dheer, phenolphthalein waxay ka heleysaa codsi baarista caafimaadka, gaar ahaan ogaanshaha cilladaha mindhicirka.Waxaa loo isticmaalaa sidii calool jilciye, oo siinaya xal dabacsan oo waxtar u leh calool-istaagga.Marka la nuugo, phenolphthalein waxa uu maraa isbeddelka midabka pH-ku-tiirsanaanta gudaha mindhicirrada, taas oo ka caawinaysa qiimaynta hawlaha mindhicirka.
Marka laga soo tago isticmaalkeeda kiimikaad iyo dawooyinka, phenolphthalein waxa kale oo ay ka heleysaa codsiga alaabta la isku qurxiyo iyo daryeelka shakhsi ahaaneed.Xaruntan waxaa loo isticmaalaa midabada timaha iyo diyaargarowga kale ee qurxinta, taasoo bixisa midabka midabka la doonayo.Degganaanshaheeda iyo la jaanqaadkeeda qaabab kala duwan ayaa ka dhigaya doorashada ugu habboon ee kor loogu qaadayo soo jiidashada quruxda alaabta daryeelka shakhsi ahaaneed.
phenolphthalein-keena, oo leh daahir sare iyo tayo joogto ah, ayaa la soo saaray iyadoo la raacayo heerarka warshadaha adag.Waxaan hubineynaa ciribtirka wasakhda iyo wasakhowga, anagoo ku siineyna badeecad buuxineysa filashooyinka ugu sarreeya.Codsiyo badan oo kala duwan, phenolphthalein-kan waa qalab lagama maarmaan u ah xirfadlayaasha ku takhasusay dhinacyada kimistariga, daawada, iyo qurxinta.
Dalbo dalbashadaada maanta oo la kulan waxqabadka gaarka ah ee phenolphthalein CAS: 77-09-8.Ku kalsoonow saxnaanta iyo isku halaynta dhammaan baahiyahaaga waxbarasho, saynis iyo warshadeed.
