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.

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.

The use of biomaterials for gene delivery can potentially avoid many of the safety concerns with viral gene delivery. However, the efficacy of polymeric gene delivery methods is low, particularly in vivo. One significant concern is that the interior and
