Description

Hydrogen -1-(3-Sulphonatopropyl)-2-[2-[[1-(3-Sulphonatopropyl)naphtho[1,2-d]thiazol-2(1H)-ylidene]methyl]-1-butenyl]naphtho[1,2-d]thiazolium, sodium salt is a high-purity, functional organic salt belonging to the cyanine dye family, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is engineered to deliver exceptional performance as a sensitizer and spectral sensitizer in advanced imaging and optical applications. It is a critical raw material for manufacturers in the photographic, optical data storage, and biomedical imaging sectors who require precise and stable light-absorbing agents.

Application

• Photographic Sensitizer: A key component in the formulation of silver halide photographic emulsions for extending spectral sensitivity into the near-infrared region.
• Optical Data Storage: Used in the production of recordable optical discs (e.g., CD-R, DVD-R) as a light-absorbing layer for laser writing.
• Laser & Nonlinear Optics: Employed as a saturable absorber or dye in tunable dye lasers and for optical limiting applications.
• Biomedical Imaging: Serves as a precursor or active component in the synthesis of NIR-fluorescent probes and contrast agents for in vivo diagnostics.
• Solar Cell Research: Investigated as a potential photosensitizer in dye-sensitized solar cells (DSSCs) due to its broad absorption profile.
• Analytical Chemistry: Utilized as a staining agent or fluorescent marker in specific chromatographic and electrophoretic techniques.
