Upotreba

Pored njegove primarne funkcije kao indikatora, bromokrezol ljubičasto se koristi u medicinskim laboratorijama za merenje albumina^[5]. 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.
