Beneficiation of selected pesticides and an antihyperlipidemic agent via cyclodextrin complexation and co-crystallization
The applications of many bioactive molecules are limited by their undesirable physicochemical properties, such as poor aqueous solubility and low thermal stability. The agrochemicals methyl- 2,5-dichlorobenzoate (fungicide, DCB) and fenthion (insecticide), as well as the medicinal compound acipimox …
