一般描述

用于质量控制的药物二级标准品,为制药实验室及制造商制备内部工作标准品提供了一种方便、高性价的替代方案。
N-乙酰基-L-半胱氨酸是内源性氨基硫醇,是人血浆和尿液的成分。在临床应用中,它可用作通常通过吸入给药的粘液溶解剂。

应用

N-乙酰基-L-半胱氨酸可用作药物参考标准品,用于通过液相色谱-质谱(LC-MS)和分光光度法技术测定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标定应用。

生化/生理作用

抗氧化剂和黏液溶解剂(mucolytic agent)。增加细胞池的自由基清除剂。 据报道可防止神经细胞凋亡,但会诱导平滑肌细胞凋亡。抑制HIV复制。可作为微粒体谷胱甘肽转移酶的底物。

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。
