Application

Tetrahydrofuran has been used for the dissolution of poly-ε-caprolactone (PCL), during the preparation of poly-ε-caprolactone (PCL)-hydroxyapatite (HA) scaffolds. It has been used for the dissolution of 1,3-diaminopentane, during the synthesis of acrylate-terminated poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (C32)-1,3-diaminopentane (117) polymer.

General description

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. The crystal structure of this double hydrate has been investigated by three-dimensional single-crystal studies.
