CAS 605-65-2: Dansyl chloride

Description: Dansyl chloride, with the CAS number 605-65-2, is a fluorescent dye commonly used in biochemistry and molecular biology for labeling proteins and peptides. It is characterized by its sulfonamide functional group, which enhances its solubility in polar solvents. The compound appears as a yellow crystalline solid and is known for its strong fluorescence properties, particularly under ultraviolet light, making it valuable for various analytical techniques, including fluorescence microscopy and chromatography. Dansyl chloride reacts with amines to form stable dansyl derivatives, which can be used to track biomolecules in complex biological systems. Additionally, it is relatively stable under standard laboratory conditions but should be handled with care due to its potential reactivity and toxicity. Proper safety measures, including the use of personal protective equipment, are recommended when working with this compound. Overall, dansyl chloride is a versatile tool in the study of protein interactions and cellular processes.
