Description

Bis-(1,3-Diethylthiobarbituric Acid)Trimethine Oxonol is a specialized organic dye belonging to the oxonol class of polymethine compounds. This compound is valued for its strong near-infrared (NIR) absorption and fluorescence properties, making it a critical functional material for advanced photonic and electronic applications. It is primarily sought by manufacturers and researchers in the semiconductor, optical materials, and analytical chemistry sectors for its role in dye-sensitized systems and as a spectral sensitizer.

Application

• Dye-Sensitized Solar Cells (DSSCs): Acts as a key sensitizing dye to absorb a broad spectrum of light and enhance photovoltaic conversion efficiency.
• Nonlinear Optical (NLO) Materials: Used in the development of materials for optical limiting, switching, and frequency conversion due to its large molecular hyperpolarizability.
• Laser Dyes and Optical Filters: Employed in the formulation of tunable laser dyes and the manufacturing of specific optical filters for scientific and industrial equipment.
• Biomedical Imaging Probes: Serves as a precursor or core structure for developing NIR-fluorescent probes and labels for bioimaging and diagnostic assays.
• Organic Photoconductors (OPCs): Utilized as a spectral sensitizer in photoreceptors for photocopiers and laser printers to extend spectral sensitivity.
• Academic and Industrial Research: A vital reagent for studying electron transfer processes, photophysical properties, and for synthesizing novel functional dyes.

Quality Control

Every batch of our Bis-(1,3-Diethylthiobarbituric Acid)Trimethine Oxonol is produced and tested under a strict quality management system to ensure high purity, batch-to-batch consistency, and reliable performance in sensitive applications. We employ advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy for comprehensive characterization. A detailed Certificate of Analysis (COA) documenting identity, purity, and spectral properties 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider using an inert atmosphere.
