Bromocresol Purple

Description:

Bromocresol Purple is a synthetic dye and pH indicator commonly used in various biochemical applications. It appears as a yellow to purple solid, depending on the pH of the solution it is in; it transitions from yellow in acidic conditions to purple in alkaline environments, typically within a pH range of approximately 6.0 to 7.6. The compound is soluble in water and alcohol, making it versatile for laboratory use. Its chemical structure includes a brominated cresol, which contributes to its color-changing properties. Bromocresol Purple is often utilized in microbiological media, as well as in titrations and other analytical procedures to monitor pH changes. Additionally, it is important to handle this substance with care, as it can be a skin and eye irritant. Overall, Bromocresol Purple serves as a valuable tool in both educational and research settings, providing visual cues for pH levels in various chemical and biological processes.
