Product Introduction

Sulfo-Cyanine3 alkyne is a fluorescent probe featuring an alkyne functional group that participates in copper-catalyzed azide–alkyne cycloaddition reactions. This compound is commonly used in labeling chemistry, where its alkyne moiety enables conjugation to azide-functionalized biomolecules, facilitating the creation of stable triazole linkages. Its sulfo-Cyanine3 chromophore provides robust fluorescence properties, making it suitable for applications in imaging and tracking within complex biological systems.
