Chemical Structure CBPEA Structure 41105-35-5
Technical Specifications

  • Appearance: Orange crystalline solid

  • Assay (HPLC): ≥ 97.0%

  • Melting Point: 165-167°C (Typical)

  • Fluorescence: Intense Yellow-Green emission

  • Solubility: Soluble in organic solvents (Dibutyl Phthalate, etc.)
Key Performance & Applications

Premium grade fluorophore for high-efficiency chemiluminescence:

  • High-Intensity Output: The critical component for "30-minute" high-intensity Cyalume-type lightsticks.

  • Superior Quantum Efficiency: Exhibits a QE of ~0.34 in peroxyoxalate systems, outperforming standard fluorescent dyes.

  • Color Shift: The chloro-substitution shifts emission specifically to the visible Yellow-Green spectrum preferred for safety lighting.

  • Enhanced Stability: Significantly higher resistance to photobleaching compared to non-halogenated BPEA.
Packaging & Handling Standard: Fiber Drums with double PE liners / Custom packaging available.
Storage: Keep in dark, dry location away from oxidizers.
