Chrysene, 4-chloro-

Chrysene, 4-chloro- (CAS: 1950643-90-9) is an organic aromatic compound belonging to the chrysene derivative family, characterized by a tetracyclic aromatic (chrysene) skeleton with a chlorine atom substituted at the 4-position. It is a high-purity, high-stability key intermediate with strong aromatic conjugation, which is derived from the polycyclic aromatic hydrocarbon chrysene. Its unique structure endows it with excellent photoelectric properties and chemical stability, making it widely used in the synthesis of functional materials and fine chemicals[9]. It is suitable for scenarios requiring polycyclic aromatic hydrocarbon skeletons with halogen substitution, which is consistent with the structural characteristics and reaction properties of chrysene derivatives. As a halogenated polycyclic aromatic compound, it needs to be handled with caution to avoid environmental pollution.
