一般描述

该认证标准物质(CRM)根据ISO 17034和ISO/IEC 17025生产和认证。有关本CRM用途的所有信息参见分析证书。

用于质量控制的药物二级标准品,为制药实验室和制造商制备内部工作标准提供了一种方便、高性价比的替代方案。

它是广泛使用的退烧及镇痛药对乙酰氨基酚(也称扑热息痛)的杂质。

应用

该药物二级标准品也可用于以下应用:

  • 通过高效液相色谱(HPLC)分离和评估市售对乙酰氨基酚片中的对乙酰氨基酚及其工艺杂质
  • 开发和确认基于HPLC的稳定性指示方法用于测定非处方糖浆制剂中的对乙酰氨基酚、马来酸氯苯吡胺及其可能的分解产物
  • 采用四种基于化学计量的分光光度法检测和定量测定对乙酰氨基酚、盐酸去氧肾上腺素和对乙酰氨基酚杂质
  • 采用离子对反相液相色谱结合紫外检测分析对乙酰氨基酚、半水磷酸可待因和吡托非农盐酸盐的复方栓剂中的杂质
  • 开发薄层色谱结合密度测定的方法用于分离商业剂型中的对乙酰氨基酚及其相关杂质

分析说明

这些二级标准品可追溯至USP、EP(PhEur)和BP一级标准品。

其他说明

分析物的数值在批次间变化很大。
