CAS 574-64-1

Trypan red

Description:

Trypan red, with the CAS number 574-64-1, is a synthetic dye belonging to the azo dye class. It is characterized by its deep red color and is commonly used in biological and medical applications, particularly for staining cells. Trypan red is known for its ability to selectively penetrate dead cells while excluding viable ones, making it a valuable tool in cell viability assays. The dye is soluble in water and exhibits a pH-dependent behavior, with its absorption spectrum shifting based on the pH of the solution. In addition to its use in laboratory settings, Trypan red has been employed in histology and microbiology for visualizing cellular structures. However, it is important to note that Trypan red has been associated with potential toxicity, and safety precautions should be taken when handling it. Overall, its unique properties make it a significant reagent in various scientific fields, particularly in studies involving cell health and viability.
