Preparation and characterization of four solvates and three novel polymorphs of rebamipide, and investigations on the stability, solubility, and dissolution rate of the stable solid forms.
X-ray powder diffraction data, unit-cell parameters, and space group for deferasirox, C21H15N3O4, are reported [a = 8.821(7) Å, b = 26.798(2) Å, c = 7.540(4) Å, α = 90°, β = 94.655(2)°, γ = 90°, unit-cell volume V = 1776.7(3) Å3, Z = 4, ρcal = 1.396 g cm−3, and space group P21/c]. All measured lines were indexed and are consistent with the P21/c space group. No detectable impurity was observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
