🔬 Common Scientific Applications
🔬 Fluorescence microscopy / imaging: Bright blue–green emitter for labeling surfaces, droplets, microstructures, and optical alignment tasks.
🔭 Laser dye & photonics: Classical gain medium for tunable dye lasers (≈440–480 nm); used in cavity calibration, beam profiling, and photonic component testing.
📈 Fluorescence spectroscopy standards: High quantum-yield dye with well-characterized spectra for emission calibration, solvatochromic studies, and method validation.
🌊 Microfluidics & flow studies: Nonreactive fluorescent tracer for flow visualization, diffusion mapping, and mixing quantification in channels and chip devices.
⚛️ Photophysical / photochemical probes: Benchmark molecule for measuring excited-state lifetimes, quantum yields, intersystem crossing, and polarity effects.
🧲 Energy-transfer (FRET/ET) research: Serves as a donor fluorophore for studying energy-transfer efficiency and optical sensor platforms.
🧪 Analytical QC & instrument setup: Stable reference for aligning fluorescence detectors, verifying spectral response, and normalizing instrument intensity.
🎓 Teaching & demonstrations: Ideal for labs on fluorescence, spectroscopy, solvent polarity effects, and dye-laser fundamentals.
Optical Properties
⚡ Excitation (λₑₓ): ~405–430 nm (violet–blue region)
✳️ Emission (λₑₘ): ~470–500 nm (blue–green fluorescence)
📈 Behavior: Strong solvatochromism — emission shifts and intensity vary with solvent polarity and microenvironment.
R&D use only.
Spectral response depends on solvent, concentration, and instrument configuration. Verify filters/optics before quantitative work and consult the SDS/CoA for your lot.
