Cresol Red

Description:

Cresol Red is an organic compound commonly used as a pH indicator in various chemical applications. It is a member of the phenol family and is characterized by its ability to change color depending on the pH of the solution it is in, typically transitioning from yellow in acidic conditions to red in more alkaline environments. The compound is soluble in water and organic solvents, making it versatile for laboratory use. Cresol Red has a molecular formula that reflects its structure, which includes a phenolic group and a sulfonic acid group, contributing to its acidic properties. It is often utilized in biological and chemical research to monitor pH changes in experiments, as well as in various industrial applications. Safety considerations should be noted, as Cresol Red can be harmful if ingested or inhaled, and appropriate handling procedures should be followed. Overall, Cresol Red is a valuable tool in analytical chemistry for its reliable pH indicator properties.

Cresol red

CAS: 1733-12-6

Cresol red is a weak diacidic molecule and an anionic dye largely used in genetic and biochemical studies. Cresol red is commonly used to measure the pH of aqueous solutions also from environmental samples, e.g. seawater (Byrne, 1989). Cresol red shows an increased protonation in acidic water-based solutions at low temperatures (Heger, 2006). Cresol red can be used to introduce pH-sensing features to sensing materials, such as, optical fibres or nanoparticles (Islam, 2021).
