Preparation of Bromophenol Blue: The phenol red dissolved in glacial acetic acid, adding the solution of bromine dissolved in glacial acetic acid under stirring. After stirring a few minutes, dumped into the 60 °C hot water, cooled to room temperature and put overnight. Filtration, the cake was washed with glacial acetic acid and benzene, then we can get the product by drying.
Uses of Bromophenol Blue: It is used as an acid-base indicator its useful range lies between pH 3.0 and 4.6. It changes from yellow at pH 3.0 to purple at pH 4.6 and this reaction is reversible. And it is also used as a color marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis. In addition, it is also used as a dye.
When you are using this chemical, please be cautious about it as the following:
It is harmful by inhalation, in contact with skin and if swallowed. And it is irritating to eyes, respiratory system and skin, so people should not breathe dust and avoid contact with skin and eyes. Furthermore, it may cause harm to the unborn child. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If you want to contact this product, you must wear suitable protective clothing. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
