CAS 477-73-6

Safranine

Description:

Safranine, with the CAS number 477-73-6, is a synthetic dye belonging to the class of phenazine compounds. It is characterized by its vibrant red to pink color, which makes it useful in various applications, including biological staining and as a pH indicator. Safranine is soluble in water and alcohol, allowing it to be easily incorporated into different solutions. In biological contexts, it is often used to stain cells and tissues, particularly in microscopy, due to its ability to bind to nucleic acids and proteins. The dye exhibits fluorescence, which enhances its visibility under specific lighting conditions. Additionally, Safranine has been studied for its potential applications in electrochemical sensors and as a redox indicator. Its chemical structure includes a central phenazine core, contributing to its stability and reactivity. While generally considered safe for laboratory use, appropriate safety measures should be taken, as with any chemical substance, to minimize exposure and ensure proper handling.
