From: Spray drying OZ439 nanoparticles to form stable, water-dispersible powders for oral malaria therapy
DSC profiles of spray dried OZ439 NP powder after oven storage at 40 °C and 75% RH in capped vials for 6 months. Profiles are similar across 6 months, with the exception of the small peak at 90 °C, which was initially present but disappears by 6 months. This peak corresponds to sodium mesylate, which may be formed from spectator sodium and mesylate ions during drying and disappears over time due to water uptake
