产品描述

General description

N,N -二甲基甲酰胺 (DMF) 通常用作各种有机反应的溶剂。DMF 是从植物组织中分离叶绿素的有效溶剂。[2]它是有机合成中广泛使用的试剂。它在溶剂、脱水剂、还原剂、催化剂等多种反应中起作用。它是合成以 O,-CO,-NMe ,-CONMe ,-Me,-CHO 为官能团的化合物的多功能构件。[1]

Application

N,N -二甲基甲酰胺 (DMF) 可用作以下研究的溶剂:
• 从黄瓜子叶完整组织中提取含叶绿素的色素。[3]
• 从单细胞海藻细胞培养物中分离叶绿素 。4
• 作为还原剂和溶剂制备 Au@Ag 核壳纳米晶体。[4]

多种疏水性有机化合物的溶剂。

包装

PE瓶也有2.5 L
