Functional Supramolecular of Inclusion Complex of Herbicide Fluroxypyr with HPβCD

Functional Supramolecular of Inclusion Complex of Herbicide Fluroxypyr with HPβCD

In this study, hydroxypropyl-β-cyclodextrin (HPβCD) was used to form an inclusion complex with fluroxypyr to enhance water solubility and thermal stability. The inclusion complex was prepared by a saturated solution method and characterized by FT-IR, SEM, TGA, and XRD. All results...

Our research showed that HPβCD was a promising carrier for improving the properties of fluroxypyr and, thus, expanding its use in agrochemical formulations.https://www.mdpi.com/2073-4360/10/12/1294HPβCDfluroxypyrinclusion complexaqueous solubilitythermal stability
