Description

6-Chloro-2-[4-[Ethyl(2-Hydroxyethyl)Amino]Phenyl]-1-Methylbenz[Cd]Indolium Acetate is a specialized cationic dye intermediate belonging to the benz[c,d]indolium (cyanine) class of compounds. This high-purity chemical is critical for synthesizing advanced functional dyes with specific light-absorption and emission properties. It is primarily utilized by manufacturers in the photographic, optical data storage, and specialty ink industries where precise molecular engineering is required.

Application

• Synthesis of Cyanine Dyes: A key precursor for manufacturing near-infrared (NIR) absorbing and fluorescent cyanine dyes.
• Optical Recording Media: Used in the production of dyes for recordable CDs (CD-R) and DVDs (DVD-R), where specific light sensitivity is crucial.
• Photographic Sensitizers: Acts as a spectral sensitizer in silver halide photographic emulsions to extend sensitivity into desired wavelength ranges.
• Laser and Nonlinear Optics: Serves as a building block for dyes used in laser applications and nonlinear optical materials.
• Biomedical Imaging Probes: A foundational material for developing fluorescent labels and probes used in bioimaging and diagnostics.
• Security Inks and Dyes: Employed in the formulation of high-security inks for anti-counterfeiting and authentication purposes.
