Products Description
Hydroxypropyl- gamma-cyclodextrin belongs to the class of cyclodextrin derivatives, which exhibit a greater extent of solubility in water compared to their parent compounds. It is widely used in parenteral formulations and solid dosage forms to aid in the improvement of their stability, dissolution, bioavailability, etc.
Characteristics
Hydroxypropyl gamma cyclodextrin dissolves large molecules, such as cholesterol, for cell culture. It is similar to betacyclodextrin, but can dissolve larger molecules.
Application
The water solubility of hydroxypropyl – γ – cyclodextrin was further increased to 80g / 100ml (25 ℃). At the same time, the hydroxypropyl – γ – cyclodextrin was no longer a single pure product, but a mixture of multiple substitutions. It was not easy to form inclusion complex crystal precipitation when it was combined with guest molecules. In general, hydroxypropyl – γ – cyclodextrin had higher water solubility and stronger anti-oxidation ability The ability of crystallization. The solubility of γ – cyclodextrin in water is 23.2g/100ml (25 ℃), and its application is limited in some cases.
