一般描述

N-乙酰基-L-酪氨酸是氨基酸L-酪氨酸的乙酰基衍生物。与L-酪氨酸相比，它易溶于水，通常用作注射营养补充剂。[1]
用于质量控制的制药二级标准品，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。

应用

N-乙酰基-L-酪氨酸可用作药物标准品，用于通过滴定分析[2]和高效液相色谱法测定散装药物和药物制剂中的分析物。[3]
这些二级标准品是合格的认证标准物质（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

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。
该认证标准物质（CRM）根据ISO 17034 和 ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在检验报告上找到。
