==Sintesis==
Fenolftalein dapat disintesis dari kondensasi anhidrida ftalat dengan dua ekivalen fenol di bawah kondisi asam. Proses ini ditemukan oleh Adolf von Baeyer pada tahun 1871.<ref>{{cite journal | author = Baeyer, A. | date = 1871 | title = Ueber eine neue Klasse von Farbstoffen | journal = Berichte der Deutschen Chemischen Gesellschaft | volume = 4 | issue = 2 | pages = 555–558 | doi = 10.1002/cber.18710040209 }}</ref><ref>{{cite journal | author = Baeyer, A. | date = 1871 | title = Ueber die Phenolfarbstoffe | journal = Berichte der Deutschen Chemischen Gesellschaft | volume = 4 | issue = 2 | pages = 658–665 | doi = 10.1002/cber.18710040247 }}</ref><ref>{{cite journal | author = Baeyer, A. | date = 1871 | title = Ueber die Phenolfarbstoffe | journal = Polytechnisches Journal | volume = 201 | issue = 89 | pages = 358–362 | url = http://dingler.culture.hu-berlin.de/article/pj201/ar201089 }}</ref>
