一般描述

乙醇是一种无色易燃的化学品,它是酒精饮料中最常见的醇类之一。它常被称为酒精。

应用

乙醇已被用于:
  • 进行小鼠实验所需的溶媒对照
  • 在刺激后和结晶紫一起对人和小鼠高级别浆液性卵巢癌(HGSOC)细胞染色进行活力检测
  • 用于制备细胞培养实验中使用的17β-雌二醇(E2)
  • 在细胞周期分析中用于固定细胞

生化/生理作用

乙醇是在工业和消费品中广泛使用的有机化学品。这种脂肪醇主要用作工业中的溶剂和其它化学品生产中的中间体。乙醇可用于塑料、药物、抛光剂、漆、增塑剂和化妆品。这种外用抗感染剂也用作乙二醇的解毒剂。

其他说明

可能适用相应的销售限制。适用于核酸的沉淀。

附注

1在瑞士分发和使用乙醇需要瑞士联邦酒精管理局的许可证。
