BTB Chemical Properties,Uses,Production

Chemical Properties

Dark greenish gold crystalline powder

Uses

Bromothymol Blue sodium salt has been used as a pH indicator in the yeast growth media (YPD, yeast extract peptone dextrose).

Uses

Suitable for use:

  • In preparations of pH indicator solutions
  • In phospholipid staining on tissues and cells prepared on microscopy slides

Uses

It is employed as a pH indicator which is yellow at pH ? 6.0 and blue at pH ? 7.6. It finds its major application in lithium battery, textiles and antagonists.

General Description

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.

Biochem/physiol Actions

Bromothymol Blue is a pH-indicator. It is also used for carbonic anhydrase assay due to the conversion of carbon dioxide to bicarbonate.
