一般描述

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品提供了一种方便、高性价比的替代方案。
柠檬酸是药物制剂中的一种常见成分。由于它与碳酸盐或碳酸氢盐结合产生的起泡作用,它可用于抗酸剂和洁齿剂中。柠檬酸也可用作缓冲剂,它有助于悬浮液的分散,从而确保活性成分的稳定性并增强抗氧化剂的功效。[1]

应用

无水柠檬酸可以用作参考标准品,通过分光光度法对生物流体中存在的柠檬酸浓度进行测定。[2]
无水柠檬酸可用作药物参考标准品,用于通过各种色谱技术测定药物制剂[1][3][4]和牛奶样品[4]中的分析物。
这些二级标准品是经过检验的认证标准物质(CRM)。它们适用于多种分析应用,包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他标定应用。

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

该认证标准物质(CRM)根据ISO 17034ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在分析证书上找到。
