Description

1,1,3-Trimethyl-2-((E)-2-(2-phenyl-3-[(E)-2-(1,1,3-trimethyl-1,3-dihydro-2H-benzo[e]indol-2-ylidene)ethylidene]-1-cyclopenten-1-yl)ethenyl)-1H-benzo[e]indolium perchlorate is a high-purity, specialized organic salt belonging to the cyanine dye family, recognized for its exceptional photophysical properties. This compound is critical for advanced research and development in photonics and materials science, where precise molecular structure dictates performance. It is primarily sought by manufacturers and researchers in the optical data storage, nonlinear optics (NLO), and photodynamic therapy (PDT) sectors for its role as a key functional material.

Application

• Optical Data Storage Media: As a key photosensitizer or recording layer component for high-density CDs, DVDs, and next-generation optical disks.
• Nonlinear Optical (NLO) Materials: Used in the fabrication of devices for optical switching, signal processing, and frequency conversion due to its high hyperpolarizability.
• Photodynamic Therapy (PDT) Agents: Investigated as a potential photosensitizer for cancer treatment, leveraging its ability to generate reactive oxygen species upon light activation.
• Laser Dyes and Saturable Absorbers: Employed in the tuning and mode-locking of lasers across specific wavelength ranges.
• Molecular Sensors and Probes: Utilized in the development of fluorescent chemosensors for detecting ions or biomolecules in analytical chemistry.
• Organic Photovoltaic (OPV) and OLED Research: Serves as an active layer component or a model compound in the study of charge transport and light emission.

Quality Control

Our production of this high-value specialty chemical adheres to strict cGMP and ISO 9001 guidelines to ensure batch-to-batch consistency and traceability. Every lot undergoes comprehensive analytical characterization, including HPLC for purity, NMR for structural confirmation, and elemental analysis. A detailed Certificate of Analysis (COA) specifying identity, purity, and impurity profiles 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 material is light-sensitive (store away from light) and contains a perchlorate salt, which is a strong oxidizer. It must be stored separately from combustible materials and reducing agents. Keep the container tightly sealed in a dry environment to prevent moisture absorption.
