Specifications Tetrahydrofuran (THF) is a saturated cyclic ether mainly used as an organic solvent. On long term storage it forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation. THF constitutes the key fragment of various natural products (polyether antibiotics). THF can form a double hydrate with hydrogen sulfide. Crystal structure of this double hydrate has been investigated by three-dimensional single-crystal studies. Butane-1,4-diol is formed as an intermediate during the synthesis of THF. Hot THF is useful for the dissolution of polyvinylidene chloride (PVDV).Synonyms: THF; Butylene oxide; Oxolane; Tetramethylene oxideMolecular Formula: C4H8OMolecular Weight: 72.11Linear Structural Formula: C4H8OMDL Number: MFCD00005356Purity: >=99.0%Melting Point: -108 C (lit.)Density: 0.889 g/mL at 25 C (lit.)Refractive Index: n20/D 1.407 (lit.)Application: Tetrahydrofuran may be used for the dissolution of poly-ε-caprolactone (PCL) and 1,3-diaminopentane, during the preparation of poly-ε-caprolactone (PCL)-hydroxyapatite (HA) scaffolds and acrylate-terminated poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (C32)- 1,3-diaminopentane (117) polymer, respectively.Legal Information: ReagentPlus is a registered trademark of Sigma-Aldrich Co.
