Description

Quinolinium, 1-Methyl-2-(2-((3-Methyl-2(3H)-Benzothiazolylidene)Methyl )-1-Butenyl)-, Iodide is a specialized organic salt belonging to the cyanine dye family, valued for its unique photophysical properties. This compound is a critical intermediate and functional material in advanced research and industrial applications where light absorption and emission characteristics are paramount. It is primarily sought by manufacturers and research institutions in the photographic, optical data storage, and dye-sensitized solar cell (DSSC) sectors.

Application

• Photosensitizer in Dye-Sensitized Solar Cells (DSSCs): A key component for absorbing sunlight and initiating electron transfer in next-generation photovoltaic devices.
• Optical Data Storage Media: Used in the formulation of recording layers for high-density optical disks due to its specific light-responsive properties.
• Photographic Sensitizing Dye: Enhances the spectral sensitivity of silver halide photographic emulsions, particularly in the near-infrared or specific visible light ranges.
• Non-Linear Optical (NLO) Materials: Serves as a building block for materials used in photonics, optical switching, and frequency conversion applications.
• Biomedical Imaging Probes: Investigated for use as a fluorescent marker or contrast agent in cellular and molecular imaging research.
• Chemical Synthesis Intermediate: Employed in the synthesis of more complex cyanine dyes and functional organic molecules.

Quality Control

Our production of this specialty cyanine dye adheres to strict batch-to-batch consistency protocols. Quality is verified through comprehensive analytical techniques including HPLC for purity, UV-Vis spectroscopy for absorbance profile confirmation, and NMR for structural identity. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to ensure it meets your specific research or formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. Keep away from incompatible materials.
