CAS 92-31-9

Toluidine Blue O

Description:

Toluidine Blue O, with the CAS number 92-31-9, is a synthetic dye belonging to the thiazine class of compounds. It is characterized by its deep blue color and is commonly used as a biological stain in histology and cytology due to its ability to bind to nucleic acids and certain proteins. The dye exhibits metachromasia, meaning it can change color when bound to different types of tissues or cellular components, which enhances its utility in microscopy. Toluidine Blue O is soluble in water and alcohol, making it versatile for various applications. In addition to its staining properties, it has been explored for its potential use in photodynamic therapy due to its ability to generate reactive oxygen species upon light activation. Safety considerations include its potential to cause skin and eye irritation, and it is advisable to handle it with appropriate protective measures. Overall, Toluidine Blue O is a valuable tool in both research and clinical settings for visualizing cellular structures.

Tolonium chloride

CAS: 92-31-9

Tolonium chloride is a chemical compound used as an optical sensor for the measurement of water vapor. It has been shown to be effective against a number of microorganisms, including bacteria and fungi. Tolonium chloride is used in a model system to study the structural analysis of biological samples. It has also been used as an antimicrobial agent in various industries, such as textiles and food processing. The mechanisms by which tolonium chloride kills microorganisms are not well understood. However, it is believed that the reaction produces nitrite ions that react with magnesium salt at high temperatures to form nitric oxide gas (NO). This gas reacts with oxygen to produce ozone, which damages bacterial cell membranes and kills the microbes. Tolonium chloride can be activated by mixing it with a strong acid, such as nitric acid or sulfuric acid, which creates an electrochemical process that can be monitored using electrochemical impedance spectroscopy.
