Structural and dynamic characterization of solid furosemide polymorphs by NQR and NMR methods

- Dynamic and structural characterization of pharmaceutical compounds by 35Cl NQR.
- 35Cl NQR characterization of form 1, 2 and HTP of furosemide.
- Experimental evidence of disorder in form 2, even at low temperatures.
- Experimental evidence of conformational motion of SO2NH2 group and NH2 in form 2.
- Slow phase transformation kinetics from form 2 to HTP.
