improving the crystal stabilities of hydrates. Furthermore, the hydration of Form B was investigated to understand the integration of water molecules by measuring the critical hydration water activities (aw). The results indicated that both water activities and temperature are vital factors to determine the amount of water molecules existing in crystal lattice. Moreover, to probe the disintegration of water
水合物在药物开发中很常见,水合物的形成会影响最终产品的性能。但是,水在晶体堆积中所起的作用仍不清楚。在这项研究中,选择具有一种二水合物(形式E),一种一水合物(形式A)和两种无水形式(形式B和D)的阿维巴坦钠作为模型化合物,以了解该主题。获得四种固体形式的单晶结构,并通过单X射线衍射表征。动态蒸气吸附实验表明,与水有关的稳定性按以下顺序增加:B型
