一般描述
用于质量控制的经认证的药物二级标准为制药实验室和制造商提供了一种方便且具有成本效益的内部工作标准品替代品。
应用
α-高生育酚乙酸酯可以用作使用高效色谱(HPLC)测定人血清或血浆样品中α-生育酚的内标。此外,还可用作药物参考标准品,以通过分光光度技术量化药物制剂中的分析物。
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校准需求。
分析说明
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
