Description

1,1'-Dibutyl-3,3,3',3'-Tetramethylindocarbocyanine Iodide is a near-infrared (NIR) fluorescent dye belonging to the cyanine family. This compound is valued for its strong light absorption and emission properties, making it an essential tool for advanced optical applications. It is primarily needed by researchers and manufacturers in the fields of biotechnology, medical diagnostics, and materials science for applications such as fluorescence labeling and imaging.

Application

• Fluorescent Labeling Agent: Used as a covalent or non-covalent tag for biomolecules (e.g., proteins, nucleic acids) in assay development.
• Biological Imaging: Serves as a contrast agent for in vitro and in vivo fluorescence microscopy and bioimaging in the NIR window.
• Laser Dye: Functions as a gain medium in tunable dye lasers due to its photostability and emission range.
• Optical Sensor Development: Incorporated into chemical sensors and probes for detecting ions, pH, or specific analytes.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in cancer treatment research.
• Non-Linear Optics (NLO): Used in research on materials for optical limiting, switching, and data storage.
• Solar Cell Research: Applied in the development of dye-sensitized solar cells (DSSCs) as a light-harvesting component.

Quality Control

Our 1,1'-Dibutyl-3,3,3',3'-Tetramethylindocarbocyanine Iodide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing all 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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment away from direct light exposure to maintain stability and performance.
