Description

4,5:4'',5''-Dibenzo-1,1''-Dibutyl-3,3,3'',3''-Tetramethylindatricarbocyanine Hexafluorophosphate is a specialized near-infrared (NIR) fluorescent dye belonging to the cyanine family, valued for its high molar absorptivity and fluorescence quantum yield. This compound is engineered for advanced photonic and analytical applications where deep tissue penetration and minimal background interference are critical. It is primarily sought by researchers and product developers in the fields of biomedical imaging, optical data storage, and non-destructive material testing.

Application

• Fluorescent Labeling and Probes: Used as a covalent or non-covalent tag for biomolecules (proteins, nucleic acids) in bioassays and live-cell imaging.
• In Vivo and In Vitro Imaging: Serves as a contrast agent for deep-tissue fluorescence imaging and microscopy due to its NIR emission window.
• Optical Data Storage: Acts as a light-absorbing material in the development of high-density optical recording media.
• Laser Dye and Photonics: Utilized as a gain medium in tunable dye lasers and in the fabrication of photonic devices.
• Sensor Development: Incorporated into chemical sensors and biosensors for the detection of ions, gases, or specific analytes.
• Material Science Research: Applied in studies of energy transfer, polymer characterization, and as a model compound for photophysical studies.

Quality Control

Our production of this high-purity cyanine dye adheres to stringent quality protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity verification, NMR and mass spectrometry for structural confirmation, and spectrophotometry for optical property validation. A detailed Certificate of Analysis (COA) is provided with each shipment, ensuring traceability and compliance with research-grade material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) for long-term stability. This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation.
