Description

2-((E)-3-(5,5-Dimethyl-3-[(E)-3-(1,3,3-trimethyl-1,3-dihydro-2H-indol-2-ylidene)-1-propenyl]-2-cyclohexen-1-ylidene)-1-propenyl)-1,3,3-trimethyl-3H-indolium perchlorate is a high-purity, functional cyanine dye salt, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is critical for applications requiring precise light absorption and emission characteristics in advanced technological fields. It is primarily sought by manufacturers and researchers in the optical data storage, laser technology, photodynamic therapy, and non-linear optics sectors.

Application

• Optical Data Storage Media: As a key light-absorbing component in recordable (CD-R, DVD-R) and high-density optical discs.
• Laser Dyes & Optical Filters: For tuning laser wavelengths and manufacturing specialized optical filters and switches.
• Photodynamic Therapy (PDT): As a potential photosensitizer agent for targeted medical treatments.
• Non-Linear Optical (NLO) Materials: In the development of materials for frequency doubling, optical limiting, and electro-optic modulation.
• Biomedical Imaging & Sensing: As a fluorescent probe or label in NIR fluorescence imaging and bio-sensing applications.
• Solar Cell Research: As a light-harvesting material in dye-sensitized solar cells (DSSCs) and organic photovoltaics.

Quality Control

Our production of this cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Every lot is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy to confirm identity, purity, and optical properties. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications 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). Due to its perchlorate salt nature and light-sensitive properties, keep away from heat, ignition sources, and incompatible materials. The container must be kept tightly sealed in a dry environment to prevent moisture absorption.
