Description

Furan (CAS 110-00-9 ), also known as furfurane or tetrole, is a five-membered oxygen-containing heterocyclic compound used as a reactive building block and solvent in chemical synthesis. Its primary commercial role is as a precursor and intermediate in the production of specialty polymers and pharmaceutical compounds. In polymer chemistry, it serves as a monomer in Diels-Alder-based systems. This enables the production of thermally reversible resins and bio-based plastics with controlled crosslinking behavior. Pharmaceutical manufacturers use it as a synthetic intermediate in the construction of drug scaffolds. Its ring structure is frequently incorporated into active pharmaceutical ingredients. As a low-boiling solvent, it is employed in laboratory-scale and pilot-plant synthesis where rapid removal is a requirement. Furan also functions as a starting material for producing tetrahydrofuran (THF) and other downstream derivatives used across solvent and polymer supply chains. It is supplied as a stabilized liquid. The product is typically available in research-grade and technical-grade specifications. It is offered in packaging ranging from small laboratory quantities to bulk drum supply, depending on purity requirements. Buyers should confirm stabilizer content and purity grade, commonly 99%+, when specifying for pharmaceutical or polymer synthesis applications to ensure consistent performance in sensitive reactions.
