Description

4,5:4',5'-Dibenzo-1,1',3,3,3',3'-Hexamethylindacarbocyanine Hexafluorophosphate is a high-purity, near-infrared (NIR) absorbing cyanine dye salt, valued for its exceptional photostability and intense fluorescence. This compound is critical for advanced research and development in fields requiring precise optical detection and labeling. It is primarily sought by manufacturers and researchers in the biotechnology, medical diagnostics, and materials science sectors for applications in fluorescence imaging, sensor development, and as a key component in photonic devices.

Application

• Fluorescent Labeling and Staining: Used as a NIR fluorescent probe for labeling biomolecules (e.g., proteins, nucleic acids) in bioassays and cellular imaging due to its high molar absorptivity and emission in the NIR region.
• Optical Imaging and Diagnostics: Serves as a contrast agent or dye in the development of in vivo and in vitro diagnostic tools, leveraging its deep tissue penetration and low background interference.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in PDT for cancer treatment, where its light-activated properties can be harnessed to generate reactive oxygen species.
• Non-Linear Optics and Photonics: Employed in the fabrication of advanced optical materials, laser dyes, and organic light-emitting diodes (OLEDs) for its specific electronic and photophysical characteristics.
• Sensor Technology: Integrated into chemical and biological sensors to detect specific analytes through fluorescence quenching or enhancement mechanisms.
• Academic and Industrial R&D: A vital reagent for fundamental research in photochemistry, supramolecular chemistry, and the development of new functional dyes.
