Tetrabromophenolphthalein ethyl ester

Description:
Tetrabromophenolphthalein ethyl ester, with the CAS number 1176-74-5, is a synthetic organic compound that belongs to the class of brominated phenolphthalein derivatives. It is characterized by its distinctive deep red color, which is a result of the presence of multiple bromine atoms attached to the phenolphthalein structure. This compound is primarily used as a pH indicator, exhibiting a color change in response to varying pH levels, making it valuable in titrations and other analytical chemistry applications. Tetrabromophenolphthalein ethyl ester is soluble in organic solvents but has limited solubility in water, which is typical for many brominated compounds. Its stability and reactivity can be influenced by environmental factors such as light and temperature. Additionally, due to its brominated nature, it may pose environmental and health concerns, necessitating careful handling and disposal. Overall, this compound serves as an important tool in laboratory settings for monitoring pH changes and conducting various chemical analyses.
