Honeywell Tetrahydrofuran Reagent Grade, =99.0%, Contains 250 Ppm Bht As Inhibitor, 1 L, Each

Details:

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.
