General description
(2-Hydroxypropyl)-α-cyclodextrin is a hydroxyalkyl derivative of cyclodextrin, which is generally used as a substitute of α-cyclodextrin for potential application in food, cosmetics and pharmaceutical industries. It may be used as a parenteral drug carrier on account of its attractive characteristics such as: a greater extent of solubility in water, high dissolution capacity for weakly soluble analytes, and low toxicity.
Application
- (2-Hydroxypropyl)-α-cyclodextrin can be used as a chiral selector to resolve tryptophan racemate by capillary electrophoresis.
- It can be used to synthesize biodegradable polyrotaxanes for fabricating blood-contacting devices.
- Co-polymer based on (2-hydroxypropyl)-α-cyclodextrin cross-linked with polyethylenimine can be used as a gene delivery vector.
- It can also be used as stabilizer for antibacterial iodine formulations, as it forms a stable inclusion complex with iodine and improves aqueous solubility.
