一般描述

该认证标准物质(CRM)根据ISO 17034和ISO/IEC 17025生产和认证。有关本CRM用途的所有信息参见分析证书

用于质量控制的药物二级标准品,为制药实验室和制造商制备内部工作标准提供了一种方便、高性价比的替代方案。

2-苯氧乙醇是一种常用的广谱抗菌防腐剂,在化妆品和局部用药物制剂中使用的浓度范围为0.5–1.0%。 它通过抑制线粒体中电子传递与磷酸化反应的耦合来起作用,并破坏ATP合成。 它也阻断苹果酸脱氢酶的活性,并提高细胞膜对钾离子的通透性。

应用

药物二级标准品也可用于以下应用:
  • 通过液相色谱-串联质谱(LC-MS/MS)测定大鼠血浆、尿液和7种不同组织样品中的苯氧乙醇及其主要代谢产物苯氧基乙酸
  • 开发用于定量测定市售人疫苗中2-苯氧乙醇的反相超高效液相色谱(RP-UHPLC)法
  • 通过高新液相色谱-光电二极管阵列- 电喷雾电离质谱法(HPLC-PDA-ESI/MS)筛查化妆产品(CPs)中17种应用广泛的防腐剂
  • 进行奶油样品中醋酸氢化可的松和2-苯氧乙醇的薄层色谱(TLC)-密度测定
  • 通过配备程序升温气化(PTV)进样口和火焰离子化检测器的气相色谱(GC)分析局部用制剂中的八种挥发性和半挥发性成分。

分析说明

这些二级标准提供了有效的美国药典、欧洲药典和英国药典一级标准的多重可追溯性。
