Fenolftalein, C20H14O4 formülüne sahip kimyasal bir bileşiktir ve genellikle kısa gösterimde "HIn" veya "phph" olarak yazılır. Genellikle titrasyonlarda kullanılır, asidik çözeltilerde renksiz, bazik çözeltilerde pembe olur. Göstergenin konsantrasyonu özellikle güçlü ise, mor görünebilir. Güçlü bazik çözeltilerde fenolftalein pembe rengi oldukça yavaş solma reaksiyonuna girer ve tekrar renksiz hale gelir.
