Safranin
Based on 1 Customer Validation
Safranin (Safranin T) is an important and classical phenazinium dye. Safranin has been extensively used in the academic field as a spectroscopic probe and indicator. Safranin possesses a planar structure and cationic charge. Safranin can readily intercalate into biological macromolecules, including DNA and proteins. Safranin has antibacterial effects against gram-positive bacteria (S. aureus). Safranin can be used as a redox indicator in the determination of metal ion concentration.
