CAS 115-39-9: Bromophenol Blue

Description: Bromophenol Blue is a synthetic dye commonly used as a pH indicator in various biochemical applications. It appears as a dark blue or purple powder and is soluble in water, exhibiting a color change from yellow at acidic pH levels to blue at alkaline conditions, typically around pH 3.0 to 4.6. This property makes it valuable in laboratory settings, particularly in gel electrophoresis, where it helps visualize the progress of DNA or protein separation. The compound has a molecular formula of C19H10Br4O5S and features a sulfonic acid group, which enhances its solubility in aqueous solutions. Bromophenol Blue is also utilized in various staining procedures and as a tracking dye in biochemical assays. While it is generally considered safe for laboratory use, appropriate safety measures should be taken, as with any chemical substance, to minimize exposure and environmental impact.
