Dansyl chloride 是一种能够在脂族和芳族胺与伯氨基反应，并产生稳定蓝色或蓝绿色荧光磺酰胺加合物的试剂，广泛用于修饰氨基酸、蛋白质测序和氨基酸分析。

Dansyl chloride reacts with primary amino groups in both aliphatic and aromatic amines to produce stable blue- or blue-green-fluorescent sulfonamide adducts. It is widely used to modify amino acids, specifically, protein sequencing and amino acid analysis.
