Description

1,1',3,3,3',3'-Hexamethyl-4,4',5,5'-Di-Benzo-2,2'-Indotricarbocyanine Perchlorate is a specialized near-infrared (NIR) cyanine dye salt, valued for its exceptional photophysical properties. This compound is critical for applications requiring deep tissue penetration and minimal background interference due to its strong absorption and fluorescence in the NIR region. It is primarily sought by researchers and manufacturers in the biotechnology, medical diagnostics, and advanced materials sectors for developing sensitive probes and functional materials.

Application

• Fluorescent Labeling and Bioimaging: Used as a NIR fluorescent tag for antibodies, proteins, and nucleic acids in in vivo and in vitro imaging applications.
• Optical Sensing: Serves as a key component in the development of chemical and biological sensors for detecting ions, gases, and biomolecules.
• Photodynamic Therapy (PDT): Investigated as a potential photosensitizer for cancer treatment due to its ability to generate reactive oxygen species upon light activation.
• Non-Linear Optics (NLO): Employed in research for optical limiting, frequency doubling, and other photonic applications.
• Dye-Sensitized Solar Cells (DSSCs): Acts as a light-harvesting sensitizer on semiconductor surfaces to improve photon-to-electron conversion efficiency.
• Laser Dye: Can be used as a gain medium in tunable dye lasers operating in the near-infrared spectrum.

Quality Control

Our production of this high-purity functional dye adheres to stringent quality protocols. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and Mass Spectrometry to confirm identity, purity, and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing spectral properties (λabs, λem, ε), purity, and residual solvent levels is provided with each shipment to ensure it meets your research and development specifications.

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 material is light-sensitive (store away from light) and the perchlorate salt is a strong oxidizer; keep away from heat, sparks, and combustible materials. For long-term stability, consider storage under an inert atmosphere such as argon or nitrogen.
