Description

Hydrogen 1-(3-Sulphonatopropyl)-2-[[3-(3-Sulphonatopropyl)Benzothiazol-2(3H)-Ylidene]Methyl]Quinolinium is a specialized, high-purity cyanine dye derivative, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is essential for applications requiring precise optical characteristics and excellent water solubility due to its sulphonatopropyl functional groups. It is primarily utilized by manufacturers in the biotechnology, medical diagnostics, and advanced materials sectors for developing sensitive detection assays and functional optical materials.

Application

• Fluorescent Labeling Reagent: Used as a covalent tag for biomolecules (proteins, antibodies, nucleic acids) in fluorescence immunoassays (FIA) and flow cytometry.
• Biosensor Development: A key component in the fabrication of optical biosensors and test strips for clinical and environmental diagnostics.
• Non-Linear Optical Materials: Serves as a dopant or building block for advanced polymers and crystals used in photonics and laser technology.
• DNA/Protein Staining: Employed in gel electrophoresis and blotting techniques for the visualization of biomolecules.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in cancer treatment research due to its light-absorbing properties.
• Industrial Dye: Applied in specialized niche areas requiring NIR-absorbing dyes for security inks or optical filters.

Quality Control

Our Hydrogen 1-(3-Sulphonatopropyl)-2-[[3-(3-Sulphonatopropyl)Benzothiazol-2(3H)-Ylidene]Methyl]Quinolinium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via UV-Vis and NMR spectroscopy, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) with detailed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation and maintain product integrity.
