Description

2-((E)-3-[1-(3-[[3-(DIMETHYL(3-[4-[(E)-3-(3-METHYL-1,3-BENZOTHIAZOL-3-IUM-2-YL)-2-PROPENYLIDENE]-1(4H)-PYRIDINYL]PROPYL)AMMONIO)PROPYL](DIMETHYL)AMMONIO]PROPYL)-4(1H)-PYRIDINYLIDENE]-1-PROPENYL)-3-METHYL-1,3-BENZOTHIAZOL-3-IUM TETRAIODIDE is a specialized, high-purity cyanine dye salt, distinguished by its symmetrical polymethine structure and four iodide counterions. This compound is engineered for applications requiring exceptional photostability and intense near-infrared (NIR) absorption, making it a critical component in advanced optical systems. It is primarily utilized by researchers and manufacturers in the biotechnology, medical diagnostics, and semiconductor industries for its unique light-interacting properties.

Application

• NIR Fluorescent Labeling and Probes: Used as a core chromophore for labeling biomolecules (antibodies, nucleic acids) in flow cytometry, fluorescence microscopy, and in vivo imaging due to its deep tissue penetration.
• Optical Data Storage and Photonics: Serves as a light-absorbing material in the development of advanced optical filters, laser dyes, and non-linear optical (NLO) devices.
• Semiconductor and Sensor Manufacturing: Employed in the fabrication of organic photodetectors (OPDs) and chemical sensors that operate in the near-infrared spectrum.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer agent for targeted cancer treatments, leveraging its ability to generate reactive oxygen species upon light activation.
• Analytical Chemistry Standards: Used as a reference standard or calibration marker in spectroscopic and chromatographic methods for quality control in chemical synthesis.

Quality Control

Every batch of this cyanine dye is manufactured under strict quality control protocols to ensure consistency and high performance for sensitive applications. We provide comprehensive Certificates of Analysis (COA) that detail purity, absorbance/fluorescence profiles, and impurity levels. Our quality systems are designed to support research and GMP-grade manufacturing needs, with traceability and documentation available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. Long-term storage under inert atmosphere (argon or nitrogen) is recommended for optimal stability.
