一般描述

六甲基二硅氮烷(HMDS)是市售甲硅烷基化剂,可用作制备甲硅烷基醚的羟基化合物替代。

应用

更多信息请参见产品信息
六甲基二硅氮烷适用于醇类、Υ-氨基丁酸、氨基甲酸酯类杀虫剂和尿素、3,4-二羟基苯乙二醇、4-羟基香豆素、羟基脂肪酸、n-羟基-2-芴基乙酰胺、kerb 酸循、丙二醛、单甘酯、苯丙酮酸、莽草酸、不饱和脂肪酸酯(或甲酯)和相关化合物衍生化。

可用作衍生试剂,通过气相色谱/质谱法(GC/Ms)分析生物胺及其酸性代谢物、 苯酚、尿液样品中的对苯二酚和儿苯酚、 油漆样品中游离脂肪酸和金属皂的混合物
适用于醇类、Υ-氨基丁酸、氨基甲酸酯类杀虫剂和尿素、3,4-二羟基苯乙二醇、4-羟基香豆素、羟基脂肪酸、n-羟基-2-芴基乙酰胺、kerb 酸循环、丙二醛、单甘酯、苯丙酮酸、莽草酸、不饱和脂肪酸酯(或甲酯)和相关化合物衍生化。

特点和优势

  • HMDS价格便宜,沸点相对较低(124-127°C)。        
  • 可以在无溶剂的情况下使用,可通过各种(大部分是酸性)催化剂提高其甲硅烷基化能力。        
  • 反应完成时,唯一的反应副产物氨会离开反应混合物。

其他说明
