Chlorophenol red

Description:

Chlorophenol red is an organic compound commonly used as a pH indicator in various chemical applications. It is characterized by its ability to change color in response to pH variations, typically transitioning from yellow at acidic pH levels to red at more alkaline conditions. This property makes it valuable in laboratory settings for monitoring pH changes in solutions. Chlorophenol red is a synthetic dye, and its chemical structure includes a phenolic group, which contributes to its acidic properties. It is soluble in water and exhibits good stability under normal conditions, although it can degrade under extreme pH or temperature conditions. In addition to its use in pH indicators, chlorophenol red can also serve as a biological stain and is utilized in microbiological assays. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled. Overall, chlorophenol red is a versatile and widely used chemical in both research and industrial applications.

Chlorophenol red

CAS: 4430-20-0

Chlorophenol red is a fluorescent probe that can be used in the detection of microbial infection. It has been shown to react with malonic acid (MAA) and fluoresce at an excitation wavelength of ~480 nm and emission wavelength of ~520 nm. The linear calibration curve for this assay was generated using human serum, which is a good model system for detecting infectious diseases. Chlorophenol red was also shown to bind to the receptor activity on mammalian cells and can be used as a marker for autoimmune diseases.
