Sulphosuccinimidyl 2-(7-azido-4-methylcoumarin-3-acetamide)ethyl-1,3-dithiopropionate (CAS 1172490-00-4)

Sulphosuccinimidyl 2-(7-azido-4-methylcoumarin-3-acetamide)ethyl-1,3-dithiopropionate (SS-7-Azido-4-methylcoumarin-3-acetamide) is a specialized compound designed for the intricate task of labeling biomolecules, particularly proteins, through a mechanism that involves the covalent attachment of the azido-modified coumarin to target molecules. This process is facilitated by the presence of a dithiopropionate linkage and the reactive succinimidyl ester, which together enable the efficient and selective conjugation to amino groups within proteins. The azido group of the compound serves as a unique handle for subsequent click chemistry reactions, a modern and highly versatile method for creating covalent bonds between molecules under mild conditions. This makes Sulphosuccinimidyl 2-(7-azido-4-methylcoumarin-3-acetamide)ethyl-1,3-dithiopropionate a powerful tool in the field of chemical biology for the fluorescent labeling of proteins, enabling researchers to visualize and track the behavior of these proteins in complex biological systems with high specificity and sensitivity. The compound′s utility is particularly notable in the study of protein-protein interactions, localization, and trafficking within cells, providing invaluable insights into the dynamic processes that underlie cellular function and organization.
