Bromthymol blue sodium

Description:
Bromthymol blue sodium, with the CAS number 34722-90-2, is a pH indicator commonly used in various chemical and biological applications. It appears as a yellow-green crystalline powder that is soluble in water and exhibits a distinct color change depending on the pH of the solution. Specifically, it transitions from yellow in acidic conditions (pH below 6.0) to blue in alkaline conditions (pH above 7.6), making it useful for visualizing pH changes in titrations and other experiments. The compound is often employed in laboratory settings, particularly in microbiology and biochemistry, to monitor pH levels in culture media. Additionally, bromthymol blue is non-toxic and has a relatively low environmental impact, which makes it suitable for educational purposes. Its stability and clear colorimetric response to pH changes contribute to its widespread use in various scientific fields.
