Description

1-Icosyl-2-[(E)-3-(1-Icosyl-3,3-Dimethyl-1,3-Dihydro-2H-Indol-2-Ylidene)-1-Propenyl]-3,3-Dimethyl-3H-Indolium Perchlorate is a high-purity, near-infrared (NIR) absorbing cyanine dye salt, valued for its exceptional photostability and strong molar extinction coefficient. This compound is critical for applications requiring precise light absorption and energy transfer in advanced material systems. It is primarily utilized by researchers and manufacturers in the photonics, optical data storage, and non-linear optics industries, as well as in the development of specialized dyes and sensors.

Application

• Optical Data Storage Media: As a key light-absorbing component in recordable CD-R, DVD-R, and advanced optical discs.
• Non-Linear Optical (NLO) Materials: For use in frequency doubling, optical switching, and laser modulation devices due to its large hyperpolarizability.
• Photodynamic Therapy (PDT) Research: Acting as a potential photosensitizer in experimental cancer treatment studies.
• Laser Dye & Filter Manufacturing: For tuning laser wavelengths and creating specific optical filters.
• Molecular Sensing & Bioimaging Probes: In the development of NIR fluorescent tags and probes for biological research.
• Organic Photovoltaic (OPV) Cells: As an electron donor or acceptor material in research for next-generation solar cells.
• Security Inks & Dyes: For anti-counterfeiting applications in currency, documents, and high-value products.

Quality Control

Our production of 1-Icosyl-2-[(E)-3-(1-Icosyl-3,3-Dimethyl-1,3-Dihydro-2H-Indol-2-Ylidene)-1-Propenyl]-3,3-Dimethyl-3H-Indolium Perchlorate adheres to a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and elemental analysis. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and compliance with your 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). This material is hygroscopic (moisture-sensitive) and a strong oxidizer; it must be kept in a desiccated environment and stored separately from combustible materials and reducing agents.
