Description

2-[2-[[3-(2-Carboxyethyl)-6-Methoxy-3H-Benzothiazol-2-Ylidene]Methyl]-1-Butenyl]-1-Methylnaphtho[1,2-D]Thiazolium Iodide is a specialized cyanine dye intermediate of significant commercial and research interest. This compound matters for its role as a key precursor in the synthesis of near-infrared (NIR) fluorescent dyes and sensitizers, which are critical for advanced imaging and energy applications. It is primarily needed by manufacturers and R&D laboratories in the photographic, optical data storage, biomedical imaging, and dye-sensitized solar cell (DSSC) industries.

Application

• Synthesis of NIR Cyanine Dyes: A crucial building block for creating polymethine cyanine dyes that absorb and emit in the near-infrared spectrum.
• Biomedical Imaging Probes: Used in the development of fluorescent labels and contrast agents for in vivo imaging, targeting, and diagnostic applications.
• Optical Data Storage Media: Serves as a key component in the formulation of recording layers for high-density optical discs and other storage technologies.
• Dye-Sensitized Solar Cells (DSSCs): Acts as a precursor for sensitizer dyes that harvest sunlight and convert it to electrical energy.
• Photographic Sensitizers: Employed in the silver halide photographic industry to extend the spectral sensitivity of emulsions.
• Laser and Nonlinear Optical Materials: Used in research for developing materials with specific lasing properties and nonlinear optical characteristics.
• Chemical Sensors: A component in the design of fluorescent chemosensors for detecting specific ions or molecules.
