Description

Hydrogen 5-Chloro-2-[2-[[5-Chloro-3-(3-Sulphonatopropyl)-3H-Benzoxazol-2-Ylidene]Methyl]But-1-Enyl]-3-(3-Sulphonatopropyl)Benzoxazolium, Sodium Salt is a high-purity, water-soluble cyanine dye derivative, essential for advanced photonic and analytical applications. Its core value lies in its strong and tunable near-infrared (NIR) absorption and fluorescence properties, making it a critical functional material. This compound is primarily needed by manufacturers and R&D teams in the biotechnology, medical diagnostics, and optical materials sectors for applications such as fluorescent labeling, optical sensors, and laser dyes.

Application

• Fluorescent Labeling and Staining: Used as a covalent or non-covalent label for biomolecules (proteins, nucleic acids) in fluorescence microscopy, flow cytometry, and bioassays.
• Optical Sensors and Probes: Serves as a key chromophore in the development of ion-selective optodes, pH sensors, and other chemical sensing platforms due to its spectral sensitivity.
• Laser Dyes and Photonic Materials: Employed in the formulation of tunable dye lasers and as an active medium in nonlinear optical materials for telecommunications and data storage.
• Medical Diagnostics: Integral to the synthesis of contrast agents and fluorescent tags for in vivo imaging and diagnostic kits.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in cancer treatment research due to its light-absorbing characteristics.
• Analytical Chemistry: Functions as a sensitive reagent in spectrophotometric and fluorometric determination methods for trace analysis.
