Dansyl chloride-d6（Cat No.:R047329）is a stable isotope-labeled version of dansyl chloride, a fluorescent dye commonly used to label amine-containing compounds such as proteins, peptides, and other biomolecules. The “d6” denotes the incorporation of six deuterium atoms, which enables precise tracking and quantification in studies using nuclear magnetic resonance (NMR) or mass spectrometry. Dansyl chloride-d6 emits a strong blue fluorescence when excited, making it useful in various applications, including protein interaction studies, enzyme assays, and biomolecular analysis. The labeled form offers enhanced sensitivity and accuracy in metabolic or structural studies.
