Product Description

Product Name	1-Chloro-9,10-bis(phenylethynyl)anthracene (CBPEA - Yellow-Green Fluorescent Agent)
CAS NO.	41105-35-5
Formula & Weight	C30H17Cl (MW: 412.91)
Chemical Structure
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.
