Aminobisphosphonates, e.g., alendronate and neridronate, are a well known class of molecules used as drugs for various bone diseases. Although these molecules have been available for decades, a detailed understanding of their most important physicochemical properties under comparable conditions is lacking. In this study, ten aminobisphosphonates, H(2)N(CH2)(n)C(OH)P(O)(OH)(2) in which n = 2-5, 7-11 and 15 have been synthesized. Their aqueous solubility as a function of temperature and pH, pK(a-) values, thermal stability, IR absorptions, and NMR spectral data for both liquid (1)H, (13)C, (31)P-NMR and solid state(13)C, (15)N and (31)P-CPMAS NMR) were determined.
氨膦酸盐，例如阿仑膦酸盐和奈立膦酸盐，是一类众所周知的分子，用作各种骨骼疾病的药物。尽管这些分子已经存在了几十年，但在可比条件下对其最重要的物理化学性质缺乏详细的了解。在这项研究中，合成了十种氨膦酸盐，H(2)N(CH2)(n)C(OH)P(O)(OH)(2)，其中 n = 2-5、7-11 和 15。测定了它们的水溶液溶解度随温度和 pH 的变化、pK(a-)值、热稳定性、红外吸收以及液体（1）H、（13）C、（31）P-NMR 和固体（13）C、（15）N 和（31）P-CPMAS NMR 的 NMR 光谱数据。
