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。抗坏血酸是一种强大的抗氧化剂,广泛用于药物制剂中。经证其对衰老相关疾病(如癌症、动脉粥样硬化、眼病、神经退行性疾病等)具有有益作用。它主要参与胶原蛋白的形成和维持。饮食长期缺乏抗坏血酸会导致坏血病。

应用

抗坏血酸可用制药参考标准品,通过亲水作用色谱定量药物制剂中的分析物。

生化/生理作用

抗坏血酸,也称为维生素C,是由植物和一些动物物种(不包括人类和其他灵长类动物)产生的六碳内酯。抗坏血酸可作为多种酶的酶促辅助因子,可用作单加氧酶和双加氧酶的电子供体。抗坏血酸还起到强力抗氧化剂的作用,特别是对活性氧。

分析说明

这些二级标准品为USP、EP(PhEur)和BP等主要标准品提供了多种可追溯性。

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。
