Description

Sulforhodamineamidoethyl Mercaptan is a specialized, high-purity chemical intermediate featuring a reactive thiol group and a fluorescent sulforhodamine moiety. This compound matters for its dual functionality, enabling covalent conjugation for labeling and its inherent fluorescence for detection and imaging. It is primarily needed by researchers and manufacturers in the life sciences, pharmaceutical development, and advanced material sectors for creating fluorescent probes, bioconjugates, and diagnostic reagents.

Application

• Fluorescent Probe Synthesis: A key building block for creating custom fluorescent labels targeting specific biomolecules like proteins, antibodies, or nucleic acids.
• Bioconjugation & Labeling: Used to covalently attach fluorescent tags to peptides, proteins, or other biological entities via its reactive mercaptan group for tracking and analysis.
• Diagnostic Reagent Development: Employed in the formulation of reagents for fluorescence-based assays, lateral flow tests, and in vitro diagnostics (IVD).
• Cell & Tissue Imaging: Serves as a precursor for developing stains and markers used in fluorescence microscopy and histology.
• Material Science Research: Utilized in surface functionalization and the development of "smart" materials where a fluorescent response is required.
• Chemical Biology Studies: Acts as a tool compound for studying thiol-reactive pathways and developing activity-based probes.
