Product Description

Hydroxypropyl-β-cyclodextrin is a chemical substance with the molecular formula (C42H70O35)-HX+(C3H7O2)X. It is a white powder with good solubility in water and can also be dissolved in 50% ethanol. There is a certain degree of relative hygroscopicity. However, the relative surface activity and hemolytic activity are relatively low. It has no irritation to muscles and is an ideal solubilizer and pharmaceutical excipient for injections.The introduction of hydroxypropyl group breaks the intramolecular cyclic hydrogen bond of β-cyclodextrin and overcomes the main shortcoming of poor water solubility of β-cyclodextrin while maintaining the cyclodextrin cavity. It is one of the most studied and widely used cyclodextrin derivatives.
