CAS 125-31-5

Xylenol blue

Description:

Xylenol blue, with the CAS number 125-31-5, is a synthetic organic compound commonly used as a pH indicator and a dye in various applications. It is characterized by its ability to change color in response to pH variations, typically transitioning from yellow in acidic conditions to blue in alkaline environments. This property makes it valuable in analytical chemistry, particularly in titrations and as a visual indicator in laboratory settings. Xylenol blue is soluble in water and exhibits a strong absorbance in the visible spectrum, which allows for easy detection and quantification. Additionally, it is often utilized in biological and environmental studies to assess the acidity or alkalinity of solutions. The compound is generally considered safe for use in laboratory settings, although appropriate safety measures should be taken to avoid ingestion or prolonged skin contact. Overall, xylenol blue serves as an important tool in both educational and professional chemistry contexts.

Xylenol Blue is a cationic surfactant that has been used as an antimicrobial agent in the treatment of analytical methods. It is also used as a polymerization initiator in the production of polyurethane plastics, and as a catalyst for organic synthesis. It is activated by radiation or hydrochloric acid, and catalyzes the reaction between cyclohexane rings and hydroxyl groups to form new molecules. This process occurs at a relatively slow rate, so it can be used in flow assays. Xylenol Blue is also applied to urine samples to detect the presence of glucose.
