Polymorphs of N-(4-chloro-3-methyl-5-isoxazolyl) 2-[2-methyl-4,5-(methylenedioxy)phenylacetyl] thiophene-3-sulfonamide, sodium salt

摘要

N-(4-chloro-3-methyl-5-isoxazolyl)-2-[2-methyl-4,5-(methylenedioxy)phenyl-acetyl]thiophene-3-sulfonamide, sodium salt, is provided herein in the form of three polymorphs (Forms A, B and C). Forms A, B and C are specified by the peaks in their X-ray powder diffraction patterns, their absorption peaks in their infrared absorption spectra, their peaks in their Raman spectra and their melting points.
