🔬 Common Scientific Applications
🔁 Redox indicator & mediator: Visible redox shifts in titrations; electron-shuttle in electrochemistry and catalysis assays.
🧫 Staining dye (microbiology/cytology): Contrast agent for cells, nuclei, and microorganisms in basic light microscopy.
📊 Spectrophotometric standard: Strong absorbance in the red (~660–668 nm); handy for instrument/calibration checks.
🌊 Tracer studies: Dye tracer for flow visualization, mixing tests, and permeability assays.
🔦 Photochemistry/photosensitizer: Model compound in photodynamic/ROS generation studies under red-light excitation.
🧪 Kinetics & mechanism probes: Follows redox-driven reaction progress; monitors electron-transfer pathways in test systems.
🧷 Materials & thin films: Doping/colorant in polymer/sol–gel films to study charge transport and optical response.
🧯 Decontamination/oxidation tests: Surrogate target in advanced oxidation (e.g., Fenton, photocatalysis) for process benchmarking.
