Acenaphthylene

Acenaphthylene (CAS 208-96-8, EC 205-917-1, formula C12H8) is a polycyclic aromatic hydrocarbon derived from naphthalene, carrying no assigned E-code. It is also referenced under the names acenaphthalene and NSC 59821, and is commercially available at purities of 80%, 95%, and 99%+.

In personal care and pharmaceutical formulations, acenaphthylene functions as a fragrance component and antimicrobial agent, where its aromatic ring structure contributes to biocidal activity against target microorganisms. It also serves as a catalyst precursor in organic synthesis, where its conjugated pi system facilitates specific reaction pathways in controlled chemical processes.

This material is supplied as a yellow crystalline powder in standard laboratory and bulk quantities, with grades ranging from 80%+ to 99%+ purity to suit different application requirements. Sourcing and handling are subject to REACH registration obligations within the EU. Buyers should confirm grade suitability against their internal specifications prior to procurement.
