Tetrahydrofuran (THF) is a colorless, water-miscible organic solvent widely used in laboratories for extraction, polymerization, and as a reaction medium. It’s also a key industrial solvent in adhesives, coatings, and pharmaceutical manufacturing. THF has a CAS number of 109-99-9, a molecular formula of C4H8O, and a molecular weight of 72.11 g/mol. It is stored at ambient conditions but requires careful handling due to its flammability and toxicity, carrying a **Danger** signal word. Molekula supplies Tetrahydrofuran from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
