Description

4,5:4',5'-Dibenzo-1,1'-Dibutyl-3,3,3',3'-Tetramethylindadicarbocyanine Perchlorate is a high-purity, synthetic cyanine dye salt, a critical functional material for advanced photonic and electronic applications. Its value lies in its exceptional optical properties, including strong absorption and fluorescence in the near-infrared (NIR) region, making it indispensable for cutting-edge research and development. This compound is primarily needed by manufacturers and researchers in the fields of non-linear optics (NLO), optical data storage, laser technology, and as a specialized sensitizer or dopant.

Application

• Non-Linear Optical (NLO) Materials: A key chromophore for the development of advanced materials used in optical switching, frequency doubling, and electro-optic modulation devices.
• Optical Data Storage: Utilized as a functional dye in the research and production of high-density recordable optical media (e.g., CD-R, DVD-R).
• Laser Dye and Sensitizer: Acts as an active medium or sensitizing agent in tunable dye lasers and other laser systems operating in specific wavelength ranges.
• Photovoltaic Research: Investigated for use in dye-sensitized solar cells (DSSCs) and organic photovoltaics due to its light-harvesting properties.
• Biomedical Imaging Probes: Serves as a precursor or core structure for synthesizing NIR-fluorescent labels and probes for in vitro and in vivo imaging.
• Chemical Sensors: Employed in the fabrication of optochemical sensors for detecting specific ions or molecules based on spectral changes.
• Academic and Industrial R&D: A fundamental building block for synthetic chemists and material scientists exploring new functional dyes and organic semiconductors.

Quality Control

Every batch of our cyanine dyes is produced and analyzed under strict quality management protocols to ensure consistency and high performance for your critical applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity (HPLC), identity (IR, NMR), and moisture content. Our production adheres to cGMP principles where applicable, ensuring traceability and reliability for research and industrial-scale use.

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 compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
