Description

4,5:4',5'-Dibenzo-1,1'-Dibutyl-3,3,3',3'-Tetramethylindadicarbocyanine Hexafluorophosphate is a high-purity, near-infrared (NIR) absorbing cyanine dye salt, valued for its exceptional photostability and sharp absorption profile. This compound is critical for advanced research and development in photonics and materials science, where precise light-matter interaction is required. It is primarily sought by manufacturers and researchers in the fields of optical data storage, laser technology, and as a specialized sensitizer or dopant in functional organic materials.

Application

• Optical Data Storage Media: As a key NIR-absorbing component in recordable (e.g., CD-R, DVD-R) and advanced optical storage materials.
• Laser Dye and Optical Limiting: Used in the formulation of tunable dye lasers and devices designed for optical power limiting and sensor protection.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in biomedical research due to its deep tissue penetration capabilities.
• Non-Linear Optics (NLO): Employed in the development of materials for frequency doubling, electro-optic modulation, and other photonic applications.
• Organic Semiconductor Layers: Acts as a functional dopant or active layer in organic light-emitting diodes (OLEDs) and photovoltaic cells.
• Analytical Chemistry & Sensors: Utilized as a fluorescent probe or label in biochemical assays and chemical sensing platforms.
• Security Inks and Dyes: Incorporated into inks for anti-counterfeiting and authentication purposes due to its specific spectral signature.

Quality Control

Every batch of our cyanine dyes is produced and tested under strict quality management protocols to ensure consistency and high performance. Standard quality parameters include identity confirmation by spectroscopic methods, purity assessment by HPLC, and verification of counterion content. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment. We support compliance with relevant research and industry standards.

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 material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under low-light conditions to maintain stability and purity.
