一般描述

Bromothymol Blue is a sulfonated hydroxyquinone in acidic solutions. In alkaline solutions, it is present as a dianion that is blue with a larger conjugated system than the yellow hydroxyquinone. Both forms are lipophilic. It is also known as bromthymol blue or dibromothymolsulfonphthalein.

应用

Bromothymol blue has various applications in biology and medicine. It is suitable for demonstrating fungal hyphae within plant roots. It is used as a vital stain to trace the movement of fluids from the lymph. It is added to an agar gel microbial culture medium for enumeration ofBacillus cereus. Bromothymol blue is also used as a pH indicator due to its precise color transition properties at neutrality.
