설명

일반 설명

Tetrahydrofuran (THF) is widely employed as a solvent. It constitutes the key fragment of various natural products (polyether antibiotics). THF forms 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).

애플리케이션

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