Ethyl Red

Description:

Ethyl Red, with the CAS number 76058-33-8, is an organic compound commonly used as a pH indicator in various applications. It is characterized by its ability to change color in response to pH variations, typically transitioning from red in acidic conditions to yellow in neutral to alkaline environments. Ethyl Red is a weak acid, and its color change occurs around a pH range of approximately 4.0 to 6.0. This compound is often utilized in laboratory settings, particularly in titrations and as a dye in biological staining. Ethyl Red is soluble in alcohol and slightly soluble in water, making it suitable for various solvent systems. Additionally, it is important to handle Ethyl Red with care, as it may pose health risks if ingested or inhaled, and appropriate safety measures should be taken during its use. Overall, Ethyl Red serves as a valuable tool in both educational and research contexts for monitoring pH levels.
