What this patent protects

本发明公开了2‑(5‑溴‑4‑(4‑环丙基萘‑1‑基)‑4H‑1,2,4‑三唑‑3‑基硫基)乙酸的S构型轴手性对映体的晶型V，其使用CuKα辐射、以2θ角度表示的X射线粉末衍射光谱至少在6.20°±0.2°、12.84°±0.2°、17.46°±0.2°、17.98°±0.2°、18.71°±0.2°、21.55°±0.2°、23.40°±0.2°、23.73°±0.2°、25.85°±0.2°、30.35°±0.2°和35.66°±0.2°处存在衍射峰。相比无定形形式，晶型V热稳定性好，便于制造和存储用于治疗组织尿酸水平异常病状的药物。
