Bromocresol Green Sodium Salt (CAS 62625-32-5) is a well-established organic compound that plays a significant role in various laboratory settings. Its chemical structure, a derivative of triphenylmethane, endows it with properties that make it an excellent pH indicator and a practical tracking dye for electrophoretic techniques.

As a pH indicator, Bromocresol Green Sodium Salt is prized for its sharp and easily observable color change. It is yellow in acidic solutions (below pH 3.8) and turns blue in alkaline solutions (above pH 5.4). This distinct transition range makes it particularly useful for titrations involving weak acids and bases, where precise endpoint detection is crucial. Researchers and technicians often seek to buy this reliable indicator from trusted chemical suppliers to ensure accuracy in their analytical procedures.

Beyond its pH sensing capabilities, Bromocresol Green Sodium Salt is widely used as a tracking dye in gel electrophoresis, a fundamental technique in molecular biology. When added to DNA or RNA samples, it migrates down the gel alongside the sample, providing a visual marker of the separation progress. This allows scientists to easily monitor how far their samples have migrated without needing to stain the gel, saving time and resources. For labs that regularly perform electrophoresis, securing a consistent supply of this dye is essential.
