Product Name	1,8-Dichloro-9,10-bis(phenylethynyl)anthracene (1,8-Dichloro-BPEA \| Intense Yellow Fluorophore)
CAS NO.	51749-83-8
Formula & Weight	C30H16Cl2 (MW: 447.35)
Chemical Structure
Technical Specifications	Appearance: Orange Crystalline Solid Assay (HPLC): ≥ 97.0% Fluorescence Emission: Yellow Region Melting Point: High thermal stability Solubility: Compatible with common organic solvent systems
Key Performance & Applications	The preferred choice for high-intensity Yellow emission: Targeted Yellow Emission: The 1,8-dichloro substitution shifts the fluorescence spectrum specifically to the Yellow region, distinct from the green of standard BPEA. Chemiluminescence: Widely used in "High-Intensity" yellow lightsticks (Cyalume type) due to its exceptional quantum efficiency and brightness stability. OLED Dopant: Serves as a robust yellow fluorescent dopant or host material in Organic Light-Emitting Diodes, offering good photostability.
Packaging & Handling	Standard: Fiber Drums. Storage: Store in a cool, dry place. Keep container tightly closed to prevent moisture absorption.
