Furan

Furan (CAS 110-00-9, EC 203-727-3, formula C4H4O) is a five-membered oxygen-containing heterocyclic compound, also known under the synonyms oxole and furfuran. It carries no assigned E-code and is classified under HS code 2932 19 00 for customs purposes.

In pharmaceutical synthesis, furan serves as a key building block for constructing heterocyclic ring systems, enabling chemists to introduce oxygen-bridged scaffolds into active pharmaceutical ingredients. In polymer chemistry, it acts as a reactive monomer and polymerization initiator, participating in Diels-Alder reactions to form thermally reversible polymer networks. It also functions as a solvent and carrier in specialty formulations.

Furan is supplied in liquid form and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU trade. Buyers should confirm supplier compliance with applicable occupational exposure and classification requirements under CLP, as furan carries carcinogenicity classifications.
