Description

Acenaphthylene (CAS 208-96-8 ) is a polycyclic aromatic hydrocarbon used as a chemical intermediate and building block in specialty synthesis. It serves as a precursor in the preparation of complex organic compounds across pharmaceutical and fine chemical manufacturing. In pharmaceutical research, acenaphthylene provides a rigid aromatic scaffold for synthesizing bioactive molecules and drug candidates requiring fused-ring architecture. It functions as a catalyst precursor in certain transition-metal-catalyzed reactions. Its conjugated ring system supports ligand design and coordination chemistry. Specialty chemical manufacturers use it as an intermediate in the production of dyes, pigments, and other polycyclic aromatic derivatives. Research institutions and contract synthesis suppliers source it for the preparation of reference standards and analytical calibration materials. This is particularly important in environmental and forensic testing applications. Acenaphthylene is supplied primarily as a solid crystalline material. It is available in research and technical grades, with purity levels typically ranging from 95% to 99%+ for laboratory and synthesis applications. Packaging is generally offered in small quantities suited to specialty and research procurement. Larger lot sizes are available on request from bulk chemical distributors to meet industrial production requirements. Contact us for supply of Acenaphthylene Request Quote
