Description

3-ETHYL-2-[(E)-2-(3-((E)-2-[3-ETHYL-5-METHOXY-1,3-BENZOTHIAZOL-2(3H)-YLIDENE]ETHYLIDENE)-2-METHYL-1-CYCLOHEXEN-1-YL)ETHENYL]-5-METHOXY-1,3-BENZOTHIAZOL-3-IUM IODIDE is a specialized cyanine dye derivative, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is engineered for applications requiring precise photophysical characteristics, including high molar absorptivity and photostability. It is a critical material for researchers and manufacturers in the fields of optical data storage, laser technology, and biomedical imaging.

Application

• Optical Data Storage Media: As a key photosensitizer and recording layer component for high-density CDs, DVDs, and next-generation optical discs.
• Laser Dyes and Nonlinear Optics: Used in the formulation of tunable dye lasers and for applications in optical limiting and switching due to its NIR activity.
• Biomedical Imaging Probes: Serves as a fluorescent tag or contrast agent in bioimaging, particularly for deep-tissue imaging in the NIR window.
• Photodynamic Therapy (PDT): Investigated as a potential photosensitizer for targeted cancer treatments.
• Organic Photovoltaic (OPV) Research: Utilized in the development of light-absorbing layers for solar cells and photodetectors.
• Chemical Sensors: Acts as a signaling moiety in the development of selective sensors for ions or biomolecules.

Quality Control

Our production of this high-purity specialty dye adheres to stringent quality protocols. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy to confirm identity, purity, and critical photophysical properties. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and absorbance/fluorescence data is provided with each shipment to ensure consistency for your research and production needs.

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 tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
