Beschreibung

Allgemeine Beschreibung

2-Hydroxypropyl-β-cyclodextrin is a cyclic oligosaccharide and used as a pharmaceutical excipient to improve the stability and bioavailability of drugs.

(2-Hydroxypropyl)-β-cyclodextrin, a hydroxyalkyl derivative, is mainly used as a formulation vehicle to increase the dissolution of drugs in water for the successful delivery of medicinal agents to biological systems. It is commonly utilized as a substitute for α-, β- and γ-cyclodextrins.

Anwendung

(2-Hydroxypropyl)-β-cyclodextrin may be used:

• As an analytical standard for the determination of the analyte in pharmaceutical formulations as well as nanoparticle formulations by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC), respectively.
• To study the host-guest interaction with organic low molecular mass compounds prior to their quantification using reversed phase HPLC technique.
• As a mobile phase additive for the effective separation of β-carbolines by HPLC.
• In cyclodextrin-modified micellar electrokinetic chromatography (CD-modified MEKC) for the determination of sertraline hydrochloride and the synthesis-related products.
• As a chiral selector to resolve pantothenic acid by capillary electrophoresis.

Die Löslichkeit lipophiler Wirkstoffe steigt in wässriger Lösung linear mit der Konzentration an Hydroxypropyl-β-cyclodextrin (HBC). Der Wirkstoff bildet mit dem HBC, über dessen nicht-polaren Bereich, einen Komplex, was zur erhöhten Löslichkeit führt. Die Lösungen können lyophilisiert werden, um ein leicht lösliches Pulver herzustellen. Nichttoxisch in Kaninchen und Mäusen.
