Description

Acenaphthene (CAS 83-32-9 ) is a polycyclic aromatic hydrocarbon used as a chemical intermediate and monomer building block across pharmaceutical synthesis and polymer manufacturing. It serves as a precursor and process chemical where a fused-ring aromatic scaffold is required in the production chain. In pharmaceutical manufacturing, it functions as a synthetic intermediate. This material is essential in the preparation of active compounds requiring a naphthalene-derived carbon framework. Dye and pigment producers use it as a starting material for synthesizing colorants. These naphthalimide-based colorants are frequently applied in printing inks and packaging coatings. In polymer chemistry, it acts as a monomer or co-monomer in specialty resin systems. Controlled aromatic content influences thermal and mechanical performance in these systems. It also supports research-scale synthesis where a defined polycyclic aromatic building block is needed. Acenaphthene is supplied as a white to pale yellow crystalline solid. Standard commercial grades include technical-grade material for industrial synthesis applications and higher-purity grades. These grades are available to meet pharmaceutical intermediate requirements. Packaging typically ranges from kilogram-scale laboratory quantities to bulk drum supply for industrial procurement.
