Description

TRISODIUM 2-(2-(2-CHLORO-3-(2-(3,3-DIMETHYL-5-SULFONATO-1-(4-SULFONATOBUTYL)INDOLIN-2-YLIDENE)ETHYLIDENE)CYCLOHEX-1-ENYL)VINYL)-3,3-DIMETHYL-1-(4-SULFONATOBUTYL)-3H-INDOLIUM-5-SULFONATE is a high-purity, water-soluble cyanine dye derivative, engineered for advanced photonic and electronic applications. Its core value lies in its exceptional light-absorbing and emitting properties, making it a critical functional material for high-tech manufacturing. This compound is essential for industries requiring precise optical performance, such as optical data storage, laser technology, and specialized analytical chemistry.

Application

• Optical Data Storage Media: A key functional dye for recordable (R) and rewritable (RW) optical discs, including CD-R, DVD-R, and Blu-ray formats.
• Laser and Photonics: Used as a gain medium or saturable absorber in tunable dye lasers and other photonic devices.
• Biomedical Imaging & Diagnostics: Serves as a near-infrared (NIR) fluorescent probe or label for bioassays, flow cytometry, and in vivo imaging due to its sulfonate groups enhancing water solubility.
• Non-Linear Optics (NLO): Employed in the research and development of materials for optical limiting, switching, and frequency conversion.
• Sensitizer for Photodynamic Therapy (PDT): Investigated for its potential to generate reactive oxygen species upon light activation for targeted therapeutic applications.
• Analytical Chemistry Reagent: Functions as a sensitive chromogenic or fluorogenic agent in spectroscopic analysis and sensor development.

Quality Control

Every batch of our cyanine dye is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure high purity and batch-to-batch consistency. Specifications are aligned with the demands of advanced material and life science applications. A detailed Certificate of Analysis (COA) documenting identity, purity (HPLC), and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
