a reversible solid phase transformation, which has been confirmed by single-crystal X-ray diffraction, solid state NMR and cycling differential scanning calorimetry tests. The phase change temperature is ca. 283–293 K (10–20 °C), which is slightly lower than room temperature (298 ± 2 K/25 ± 2 °C), but is in the range of ambient temperature. This kind of near room temperature phase transformation is
摘要 阿昔洛韦是一种常用的抗病毒药物,但其溶解度远未达到令人满意的程度。据报道,1:1 阿昔洛韦-马来酸盐 (ACV-MAL) 具有更高的最大表观溶解度。在这个贡献中,在室温下解决了 ACV-MAL 的新晶体结构。这种新的晶体结构和先前报道的低温结构可以通过可逆的固相转变相互转化,这已通过单晶 X 射线衍射、固态核磁共振和循环差示扫描量热测试得到证实。相变温度约为。283–293 K (10–20 °C),略低于室温(298 ± 2 K/25 ± 2 °C),但在环境温度范围内。这种接近室温的相变关注较少,容易被忽视。
