Description

3-Butyl-2-[5-(1-Butyl-3,3-Dimethylindol-2(3H)-Ylidene)Pentane-1,3-Dienyl]-1,1-Dimethyl-1H-Benzo[E]Indolinium Perchlorate is a high-purity, functional organic salt belonging to the cyanine dye family, valued for its exceptional photophysical properties. This compound is critical for advanced research and development in photonics and materials science, where precise molecular characteristics are paramount. It is primarily sought by manufacturers and R&D laboratories in the optical data storage, nonlinear optics (NLO), and laser dye sectors, as well as for use as a sensitizer in photographic and imaging technologies.

Application

• Nonlinear Optical (NLO) Materials: A key chromophore for developing advanced materials with second- and third-order nonlinearities for optical switching and signal processing.
• Laser Dyes: Used as an active medium in tunable dye lasers, particularly in the near-infrared region, due to its specific absorption and emission profiles.
• Optical Data Storage: Employed in the research and formulation of recording layers for high-density optical disks (e.g., CD-R, DVD-R).
• Photographic Sensitizers: Functions as a spectral sensitizer in silver halide photographic emulsions to extend sensitivity into desired wavelength ranges.
• Bioimaging and Sensing Probes: Investigated for potential use in fluorescence labeling and as a component in sensor systems due to its dye characteristics.
• Organic Photovoltaic (OPV) Research: Studied as a potential electron donor or acceptor material in the development of next-generation solar cells.

Quality Control

Every batch of our cyanine dye is produced and analyzed under strict quality management to ensure consistency and high performance for sensitive optical applications. Standard quality parameters include identity confirmation by spectroscopic methods, purity assessment by HPLC, and control of critical impurities. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to support your quality assurance protocols.

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 light-sensitive (store away from light) and hygroscopic (moisture-sensitive). For long-term storage, consider desiccation and an inert atmosphere to maintain stability.
