    Description

    General description

    Tetrahydrofuran (THF) is widely employed as a solvent. It constitutes the key fragment of various natural products (polyether antibiotics).[1] THF forms a double hydrate with hydrogen sulfide. Crystal structure of this double hydrate has been investigated by three-dimensional single-crystal studies.[2] Butane-1,4-diol is formed as an intermediate during the synthesis of THF.[5] Hot THF is useful for the dissolution of polyvinylidene chloride (PVDV).[6]

    Application

    Suitable for HPLC, spectrophotometry, environmental testing

    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[3] and acrylate-terminated poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (C32)- 1,3-diaminopentane (117) polymer,[4] respectively.
