Description

1-Ethyl-2-[3-(3-Ethyl-3H-Benzoxazol-2-Ylidene)Prop-1-Enyl]Quinolinium Iodide is a high-purity cyanine dye salt, a critical functional material valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is essential for advanced research and manufacturing processes that require precise light-matter interaction. It is primarily sought by developers and manufacturers in the optical data storage, laser technology, biomedical imaging, and non-linear optics sectors.

Application

• Optical Data Storage Media: As a key photosensitizer and recording layer component for high-density CDs, DVDs, and next-generation optical discs.
• Laser Dye & Optical Limiting: Used in the formulation of tunable dye lasers and for creating devices that protect sensors from intense laser pulses.
• Biomedical Imaging & Photodynamic Therapy (PDT): Functions as a contrast agent or photosensitizer for NIR fluorescence imaging and targeted phototherapeutic applications.
• Non-Linear Optical (NLO) Materials: A building block for synthesizing organic crystals and polymers with high second or third-order non-linear optical susceptibility.
• Sensor Technology: Incorporated into chemical sensors and biosensors for the detection of specific analytes based on fluorescence quenching or enhancement.
• Photovoltaic Research: Investigated as a potential light-harvesting material in dye-sensitized solar cells (DSSCs) and organic photovoltaics.

Quality Control

Our production of this specialty cyanine dye adheres to strict quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure structural identity and purity. Certificates of Analysis (COA) detailing lot-specific purity, absorbance/fluorescence profiles, and impurity levels are provided to guarantee consistency for your critical applications.

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 dry environment to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
