M-CRESOL PURPLE, SODIUM SALT Usage And Synthesis

Chemical Properties	orange-brown to black powder
Uses	m-Cresol purple sodium salt is used to detect changes in pH during titrations at which color changes occur at pH 7.6-9.2. Upon bromination, m-cresol purple sodium salt creates the dye bromocresol green (sc-206036) which is used as a tracking dye in DNA agarose gel electrophoresis. In addition, m-cresol purple sodium salt can be used to stain epithelial cells and proteins.
