Chemical Property/Description

 

Tetrabromophenol Blue is a beige powder with a melting point of 203-205 °C (dec.)(lit.)


Main Uses:

Tetrabromophenol Blue  is one of the most sensitive reagents for detecting albumin. Because it can semi-quantitatively form a stable blue color with albumin on paper, its sensitivity exceeds that of other indicators that can produce protein errors, such as bromophenol blue, bromocresol green, and tetrabromophenolphthalein ethyl ester, etc., so it has been widely used as a reagent for the manufacture of urine protein rapid test paper in foreign countries.

Bromophenol blue indicator solution. Usage: Color range: pH2.8-4.6 (yellow-blue), acid-base indicator; Indicator for non-aqueous titration, protein electrophoresis staining; Virus tests, etc.
