Description

Cyanine 863 is a versatile near-infrared (NIR) fluorescent dye belonging to the cyanine family, identified by CAS NO 550-15-2. This compound is valued for its strong absorption and emission in the NIR region, enabling deep-tissue imaging and applications where background autofluorescence is minimal. It is an essential reagent for researchers and manufacturers in the fields of bioimaging, optical sensing, and material science, providing a critical tool for non-invasive diagnostics and advanced photonic devices.

Application

• Bioimaging & Diagnostics: Used as a fluorescent probe for in vivo and in vitro imaging, particularly for deep-tissue visualization in small animal studies.
• Optical Sensors: Incorporated into sensor platforms for detecting ions, biomolecules, or environmental analytes due to its photostable NIR signal.
• Photodynamic Therapy (PDT): Serves as a potential photosensitizer candidate for cancer treatment, leveraging its light-absorbing properties.
• Material Science: Functionalizes nanoparticles, polymers, and other materials to impart NIR fluorescence for tracking and labeling applications.
• Non-Destructive Testing (NDT): Applied in industrial settings for flaw detection and material characterization using NIR fluorescence techniques.
• Security Inks & Taggants: Utilized in the formulation of covert security inks for anti-counterfeiting and authentication purposes.

Quality Control

Our Cyanine 863 is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, UV-Vis-NIR spectroscopy for absorbance/emission verification, and identity confirmation via mass spectrometry. We provide Certificates of Analysis (COA) with every shipment, detailing all critical specifications to ensure batch-to-batch consistency and performance for your sensitive applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to ambient conditions or light may degrade performance. For long-term stability, consider storage under an inert atmosphere.
