Description

2-((E)-2-(2-(DIPHENYLAMINO)-3-[(E)-2-(1,3,3-TRIMETHYL-1,3-DIHYDRO-2H-INDOL-2-YLIDENE)ETHYLIDENE]-1-CYCLOPENTEN-1-YL)ETHENYL)-1,3,3-TRIMETHYL-3H-INDOLIUM TETRAFLUOROBORATE is a high-purity, functional organic salt belonging to the class of cyanine dyes, specifically a heptamethine indocyanine dye derivative. This compound matters for its exceptional near-infrared (NIR) absorption and fluorescence properties, making it a critical component in advanced optical applications. It is primarily needed by manufacturers and researchers in the photonics, biomedical imaging, and optical data storage industries seeking reliable, high-performance chromophores.

Application

• NIR Fluorescent Dyes & Probes: A key building block for synthesizing fluorescent labels and probes used in bioimaging, medical diagnostics, and live-cell imaging due to its deep tissue penetration and low background interference.
• Optical Data Storage: Employed in the formulation of recording layers for high-density optical discs and holographic data storage media, leveraging its specific light-absorbing characteristics.
• Laser Dyes & Photonic Materials: Used as an active medium in tunable dye lasers and as a functional component in the development of nonlinear optical (NLO) materials and organic photonic devices.
• Photodynamic Therapy (PDT) Agents: Serves as a precursor or core structure for photosensitizers designed to target and destroy cancer cells upon activation with specific light wavelengths.
• Chemical Sensors: Incorporated into sensor systems for the detection of specific ions, gases, or biomolecules, where its optical properties change upon binding with the target analyte.
• Advanced Material Research: Utilized in academic and industrial R&D for exploring new organic semiconductors, solar cell materials, and other functional organic electronic components.

Quality Control

Our production of this specialty cyanine dye adheres to stringent ISO 9001 quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and spectrophotometry to verify key optical properties. A detailed Certificate of Analysis (COA) is provided with each shipment, ensuring traceability and compliance with your specific research or manufacturing 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 nature, the container should be kept in a desiccated environment. For long-term stability, consider storage under an inert atmosphere such as argon or nitrogen.
