Description

1-Ethyl-2-[3-(1-Ethyl-2-Methyl-4(1H)-Quinolylidene)Prop-1-Enyl]-4-Methylquinolinium Iodide is a specialized cyanine dye salt, a high-value chemical intermediate prized for its distinct photophysical properties. Its primary value lies in its ability to act as a sensitizer and spectral sensitizer in advanced imaging and optical applications. This compound is essential for B2B customers in the photographic, optical data storage, and laser dye industries, where precise light absorption and emission characteristics are critical. We supply this material with a focus on batch-to-batch consistency and technical support for formulation challenges.

Application

• Spectral Sensitizer for Silver Halide Photography: Extends the spectral sensitivity of photographic emulsions into specific wavelength regions.
• Optical Data Storage Media: Used in the formulation of recordable (e.g., CD-R, DVD-R) dye layers that are written by laser light.
• Laser Dye Precursor: Serves as a key intermediate in the synthesis of dyes for tunable dye lasers.
• Non-Linear Optical (NLO) Materials: Investigated for use in applications requiring high optical nonlinearity, such as optical switching and signal processing.
• Biomedical Staining and Labeling: Potential use in developing fluorescent probes for cellular imaging and diagnostic assays due to its cyanine backbone.
• Photoelectrochemical Cells: Research component in dye-sensitized solar cells (DSSCs) for light harvesting.
