Description

Fluorescein 200% (Resorcinolphthalein)
Other Names: Fluorescein sodium (when in salt form), 3',6'-Dihydroxyspiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one
Chemical Formula: C₂₀H₁₂O₅
Molar Mass: 332.31 g/mol
CAS Number: 2321-07-5 (free acid form)
Appearance: Orange-red to dark red powder
Purity: Pure compound (technical grade, UV dye content ~200%)

Fluorescein is a synthetic organic compound from the xanthene dye group. It exhibits strong fluorescence and is used extensively as a tracer dye and UV-reactive marker in industrial and analytical contexts. In its pure acid form, it appears dark red under visible light and glows bright green under UV illumination (excitation ~490 nm, emission ~515 nm).


Chemical and Physical Properties

  • Density: ~1.6 g/cm³

  • Melting Point: ~314 °C (with decomposition)

  • Solubility in Water: Low (as free acid); forms water-soluble salts

  • Solubility in Solvents: Soluble in alcohol, alkali solutions, and polar organic solvents

  • Fluorescence: Intense green fluorescence under UV or blue light

  • Stability: Stable under normal conditions, light-sensitive


Applications

UV and Fluorescent Tracing

  • Used as a fluorescent tracer in leak detection, flow studies, and hydraulic modeling in pipelines and open water systems.

Industrial Dyeing

  • Applied in quality control, UV detection systems, and marker dyes for inks and coatings.

Analytical Chemistry

  • Employed as a pH-sensitive indicator and in fluorometric titrations.

Research and Laboratory Use

  • Utilized in imaging techniques and to label or visualize fluid movements under UV light.


Safety

Signal WordWarning

  • P337+P313: If eye irritation persists: Get medical advice/attention


Handling and Storage

  • Handling: Avoid generation of dust. Use in well-ventilated or filtered-air environments. Wear suitable protective clothing and avoid contact with skin and eyes.

  • Storage: Store in a cool, dry, and dark container, tightly sealed. Protect from direct sunlight and moisture.

  • Incompatibilities: Strong oxidizing agents, acids


Environmental Considerations

Although fluorescein is used in environmental tracing, concentrated discharge into aquatic environments should be minimized. Follow local regulations regarding disposal of dye-containing solutions.
