Description

Naphtho[2,1-d]thiazolium, 3-ethyl-2-[[3-[3-[3-[(3-ethylnaphtho[2,1-d]thiazol-2(3H)-ylidene)methyl]-5,5-dimethyl-2-cyclohexen-1-ylidene]-1-propenyl]-5,5-dimethyl-2-cyclohexen-1-ylidene]methyl]-, perchlorate is a specialized organic salt belonging to the cyanine dye family, recognized for its unique photophysical properties. This compound is valued for its strong near-infrared (NIR) absorption and fluorescence, making it a critical functional material in advanced technological applications. It is primarily sought by researchers and manufacturers in the fields of optical data storage, laser technology, and biomedical imaging.

Application

• Optical Data Storage Media: Used as a key light-absorbing component in recordable (R) and rewritable (RW) optical discs, including CD-R, DVD-R, and Blu-ray formats.
• Laser Dyes & Optical Filters: Serves as a tunable dye for solid-state and liquid lasers operating in the near-infrared spectrum, and in the fabrication of optical filters and switches.
• Non-Linear Optical (NLO) Materials: Employed in the development of materials for photonics, including optical limiters and frequency converters, due to its high polarizability.
• Biomedical Imaging & Photodynamic Therapy (PDT): Investigated as a potential photosensitizer or contrast agent for NIR fluorescence imaging and targeted phototherapeutic applications.
• Solar Energy & Photovoltaics: Used in research for organic solar cells and dye-sensitized solar cells (DSSCs) as a light-harvesting material to broaden the absorption spectrum.
• Chemical Sensors: Utilized in the design of fluorescent chemosensors for detecting specific metal ions or biological molecules based on fluorescence quenching or enhancement.

Quality Control

Our production of this high-purity functional dye adheres to strict quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy to ensure consistent spectral properties and chemical identity. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance maxima, and impurity profile is provided with every shipment to support your R&D and manufacturing quality assurance.

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 light-sensitive nature and as a perchlorate salt, the container should be kept away from heat sources, direct sunlight, and incompatible materials. Keep the container tightly sealed to prevent moisture absorption.
