Bromokrezol ljubičasto (BCP) ili 5',5"-dibromo-o-krezolsulfoftalein, je pH indikator. Najčešće se koristi kao 0.04% vodeni rastvor.

Bromokrezol ljubičasto (pH indikator)
ispod pH 5.2		iznad pH 6.8
5.2	↔	6.8

Upotreba

Pored njegove primarne funkcije kao indikatora, bromokrezol ljubičasto se koristi u medicinskim laboratorijama za merenje albumina^[6]. On se takođe koristi kao dodatak kiselim kupatilima koja se koriste u pripremi fotografija kao indikator da je kupatilo dostiglo neutralni pH i treba da bude zamenjeno.
