本发明的普拉格雷氢溴酸盐的 B型晶体的 IR (红外吸收光谱)约在 1713 , 1762 cm 处有吸收峰。
需要说明的是, 在 XRPD 中, 由晶体化合物得到的衍射谱图对于特定的晶型往 往是特征性的, 其中谱带(尤其是在低角度)的相对强度可能会因为结晶条件、 粒径 和其它测定条件的差异而产生的优势取向效果而变化。 因此,衍射峰的相对强度对所 针对的晶型并非是特征性的,判断是否与已知的晶型相同时, 更应该注意的是峰的位 置而不是它们的相对强度。 在 XRPD图谱中通常用 2Θ角或晶面距 d表示峰位置, 由 于 2Θ角与入射 X射线的波长有关, 因此用晶面距 d表示更具有代表性。 两者之间具 有简单的换算关系: d = /2sin9, 其中 d代表晶面距, λ代表入射 X射线的波长(对 于 Cu-K„, λ = 1.54187A ) , Θ为衍射角。 对于同种化合物的同种晶型, 其 XRPD谱 图在整体上具有相似性,表征峰位置的 d值误差一般在 ±2 %之内, 大部分误差不超过 ±1 %; 相对强度误差可较大, 但变化趋势一致。 另外, 判断晶型是否一样时应注意保 持整体观念, 因为并不是一条衍射线代表一个物相, 而是一套特定的" "数据才代 表某一物相。 还应指出的是, 在混合物的鉴定中, 由于含量下降等因素会造成部分衍 射线的缺失, 此时, 无需依赖高纯试样中观察到的全部谱带, 甚至一条语带也可能对 给定的晶体是特征性的。
DSC 测定当晶体由于其晶体结构发生变化或晶体熔融而吸收或释放热时的转变 温度。 对于同种化合物的同种晶型, 在连续的分析中, 热转变温度和熔点误差典型地 在约 ±5°C之内, 通常在约 ±3°C之内。 DSC提供了一种辨别不同晶型的辅助方法。 不 同的晶体形态可根据其不同的转变温度特征而加以识别。需要指出的是对于混合物而 言, 其 DSC峰或熔点可能会在更大的范围内变动。 此外, 由于在物质熔化的过程中 伴有分解, 因此熔化温度与升温速率密切相关。
IR测定分子中对应于光而振动的基团相关的特定化学键引起的红外吸收。 由于 不同晶型分子内共价键的电环境不一样,共价键强度也可能会有变化,共价键强度的 改变必然会导致不同晶型的 IR光语的不同。

角度误差 I Δ2Θ I = 0.0058。; 零点漂移 ( Zero Offset ) = 0.0。; 品质因子 F(30) = 45.3(110)。
基于较小的角度误差, 无零点漂移, 并且实验语线和理论语线位置符合良好, 本 指标化结果可靠。
该结果证明所提供样品为纯相化合物,可和所对应的实验语图可以作为分辨同一 物相的数据和指纹图谱。 实施例 9: 非溶剂化晶体的测试及指标化
样品: 实施例 6的非溶剂化晶体( B型晶体)
X-射线粉末衍射测试: 仪器型号: Bruker D8 ADVANCE; 光源: Cu-K„ 40 kV 40 mA; 石墨单色器; 发散狹缝(DS ) : 1°; 防散射狹缝(SS ) : 1°; LynxEye阵列探 测器, 扫描方式: Θ/Θ, 连续扫描; 扫描范围: 3°〜45°, 扫描速度 8°/min, 结果见图 6。
将图 6与图 1对比, 可见无论峰位置、 峰强度还是峰形均有明显的差异, 可见实 施例 6和实施例 2的晶体不同。
根据实施例 6的粉末衍射原始谱图进行指标化并精修得到的晶胞参数如下: 晶体属于正交晶系,空间群为 Pnma (62)。 a= 15.42456 A; b=7.28661 A; c=21.23884 A; α = β = γ = 90°; 晶胞体积 = 2387.09 A3。 品质因子 F(30) = 25.4(117)。
对比 A型晶体和 B型晶体: ( 1 )B型晶体的分子中比 A型晶体少一个乙酸分子, 分子量较小, 但是其晶胞体积大于 A型晶体, 其原因在于乙酸分子与普拉格雷分子 之间形成氢键, 其空间结构更加紧凑有序。 在稳定性考查中也发现, A型晶体的稳定 性要优于 B型晶体, 稳定性上的差别, 来源于空间结构上差异。 实施例 10: 影响因素试险
受试样品来源:

X2 (普拉格雷氢溴酸盐)按照 CN101255169A中实施例 1提供的方法制备
X3 (普拉格雷氢溴酸盐乙酸溶剂化物)按照本发明实施例 2的方法制备 实验方法: 参见中华人民共和国药典 2005年版二部附录 XIX C
HPLC条件: 仪器: Agilent 1100
色谱柱: Phenomenex Hyperclone 5μ BDS C18
流动相: 乙腈: KH2P04 ( 10 mM ) =70: 30
柱温: 40 °C
流速: 1.0 ml/min 波长: 220 nm
实验结果:
表 2
Figure imgf000013_0001
表 2为实施例 2的乙酸溶剂化物的稳定性分析结果。 稳定性试验结果显示, 其 ( X3 )分别在光照、 60°C、 RH 92.5%条件下均比已发现的盐酸盐晶体 (XI)及普拉格 雷氢溴酸盐 (X2 )稳定。 实施例 11: 乙酸溶剂化物的溶解性
受试样品来源: 同实施例 10
实验方法: 参见中华人民共和国药典 2005年版二部凡例
实验结果:
表 3
