Bromothymol blue

Description:

Bromothymol blue is a pH indicator commonly used in various chemical and biological applications. It is a synthetic dye that exhibits a distinct color change depending on the acidity or alkalinity of a solution. In acidic conditions, it appears yellow, while in neutral to slightly basic conditions, it transitions to green, and in more alkaline environments, it turns blue. This characteristic makes it useful for monitoring pH changes in titrations and biological experiments. The compound has a molecular formula of C27H28Br2O5S and a molecular weight of approximately 624.4 g/mol. Bromothymol blue is soluble in alcohol and slightly soluble in water, which can limit its use in certain aqueous applications. It is often employed in laboratory settings, particularly in microbiology and biochemistry, to assess the pH of culture media. Additionally, it is non-toxic and safe for use in educational settings, making it a popular choice for demonstrations and experiments involving acid-base chemistry.
