Description

4,5 Benzo-1-Butyl-1',3,3,3',3'-Penta-Methylindadicarbocyanine Tetrafluoroborate is a high-purity, functional cyanine dye derivative. This compound is valued for its strong near-infrared (NIR) absorption and fluorescence properties, making it a critical component in advanced optical applications. It is primarily sought by researchers and manufacturers in the photonics, biomedical imaging, and materials science sectors for developing sensors, probes, and functional materials.

Application

• NIR Fluorescent Probes & Labels: Used as a labeling agent for biomolecules (proteins, nucleic acids) in fluorescence microscopy and bioimaging due to its deep tissue penetration and low background interference.
• Optical Data Storage: Serves as a key photosensitive material in the development of advanced optical recording media and holographic storage systems.
• Laser Dye & Photonics: Employed as a gain medium or saturable absorber in tunable dye lasers and other photonic devices operating in the near-infrared region.
• Chemical Sensors: Integrated into sensor platforms for detecting specific ions or molecules, where its fluorescence properties change upon binding.
• Non-Linear Optical Materials: A building block for synthesizing organic crystals or polymers with enhanced non-linear optical (NLO) properties for telecommunications and optical computing.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in cancer treatment research due to its ability to generate reactive oxygen species upon light activation.

Quality Control

Our 4,5 Benzo-1-Butyl-1',3,3,3',3'-Penta-Methylindadicarbocyanine Tetrafluoroborate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectral analysis (NMR, MS) for identity confirmation, to ensure high batch-to-batch consistency and performance reliability for sensitive applications. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance/fluorescence maxima, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive) and light-sensitive; desiccants are recommended for long-term storage. Keep container tightly sealed under an inert atmosphere (argon or nitrogen) when not in use to prevent degradation.
