Description

3-Butyl-2-[5-(3-Butyl-1,3-Dihydro-1,1-Dimethyl-2H-Benz[E]Indol-2-Ylidene)-3-Chloro-1,3-Pentadien-1-Yl]-1,1-Dimethyl-1H-Benz[E]Indolium Hexafluorophosphate (1:1) is a high-purity, functional organic salt belonging to the cyanine dye family, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is critical for advanced research and development in photonics and materials science, where precise optical characteristics are paramount. It is primarily sought by manufacturers and researchers in the fields of optical data storage, laser technology, and as a sensitizer in dye-sensitized solar cells (DSSCs).

Application

• NIR-Absorbing Dye for Optical Data Storage: Used in the formulation of recording layers for high-density optical discs (e.g., CD-R, DVD-R) due to its specific light absorption profile.
• Laser Dye and Optical Limiting Materials: Serves as an active medium in tunable dye lasers and in the development of materials for protecting sensors from intense laser pulses.
• Photosensitizer for Dye-Sensitized Solar Cells (DSSCs): Employed to enhance light harvesting efficiency in the red to near-infrared spectrum for next-generation photovoltaic devices.
• Biomedical Imaging Probes: Utilized in the synthesis of fluorescent labels and contrast agents for in vivo imaging and diagnostic applications.
• Non-Linear Optical (NLO) Materials: A key intermediate for creating organic crystals and polymers with applications in telecommunications, optical switching, and frequency conversion.
• Chemical Sensing: Incorporated into sensor platforms for the detection of specific ions or molecules based on fluorescence quenching or enhancement.

Quality Control

Our production of 3-Butyl-2-[5-(3-Butyl-1,3-Dihydro-1,1-Dimethyl-2H-Benz[E]Indol-2-Ylidene)-3-Chloro-1,3-Pentadien-1-Yl]-1,1-Dimethyl-1H-Benz[E]Indolium Hexafluorophosphate (1:1) adheres to stringent in-process controls to ensure batch-to-batch consistency and high optical purity. Each lot is analyzed via HPLC, NMR, and mass spectrometry to confirm identity and quantify major impurities. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance maxima, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and light-sensitive. For long-term stability, store under an inert atmosphere (argon or nitrogen) at 2-8°C. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress.
