General description

六甲基二硅烷(HMDS)是稳定有效的氢不稳定类物质的三甲基硅烷化反应试剂，如醇、胺和脂肪酸。常用于在化学合成时保护敏感的官能基团。因其低成本、高蒸气压和安全性，广泛用作化学气相沉积(CVD)反应前体。

Application

六甲基二硅烷(HMDS)可用于：
  • 作为硅烷化剂，用于近中性条件下醇类的三甲基硅烷化反应。
  • 在α-氨基酸N-羧基酸酐的开环聚合反应中控制多肽分子量。
  • 通过等离子体增强化学气相沉积(CVD)制备碳氮化硅薄膜。
  • 用于扫描电镜的标本制备，以及羟基化合物制备三甲基硅醚。

Features and Benefits

  • 强化学稳定性和低分子量
  • 无毒性的实惠试剂
  • 硅烷化反应的唯一副产物只有氨
  • HDMS硅烷化反应近中性，无需采取任何特别措施

Critical point drying (CPD) is a common method of drying biological specimens for scanning electron microscopy (SEM). Drying by evaporation of hexamethyldisilazane (HMDS) has been described as a good alternative. This method, however, is infrequently used. Therefore, we reassessed HMDS
