一般描述

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。左旋多巴是神经递质多巴胺的代谢前体,被广泛应用于帕金森′病的治疗。

应用

左旋多巴可作为药物参考标准品,用于通过流动注射分光光度法和1H核磁共振波谱法对药物制剂中的分析物进行定量。
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

该认证参考物质(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。
