Description
Fluorene (CAS 86-73-7, EC 201-695-5, formula C13H10) is a polycyclic aromatic hydrocarbon composed of two benzene rings fused to a central cyclopentane ring. It carries no assigned E-code and is referenced in technical literature under the synonyms 9H-Fluorene and NSC 6787. It is classified as a pharmaceutical intermediate.
In pharmaceutical synthesis, fluorene serves as a carbon scaffold for building bioactive molecules, where its rigid tricyclic structure provides a stable backbone for further functionalization. In polymer chemistry, fluorene-based monomers undergo oxidative or electrochemical polymerization to produce conjugated polymers used in organic light-emitting devices. It also acts as a precursor in the production of fluorene-derived epoxy resins with high refractive indices.
Fluorene is supplied as a crystalline powder and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier compliance documentation, including safety data sheets aligned with EU GHS standards. Standard packaging formats vary by volume; consult our technical team for batch specifications and certificates of analysis.
