Description

3-(2-Carboxyethyl)-2-[2-[(5-Chloro-3-Ethyl-3H-Benzothiazol-2-Ilidene)Methyl]But-1-Enyl]-6-Methoxy-5-Methylbenzothiazolium Iodide is a high-purity, specialized benzothiazolium salt derivative, identified by CAS No. 63870-54-2. This compound serves as a critical advanced intermediate and functional dye precursor for research and industrial synthesis. It is primarily sought by manufacturers and R&D laboratories in the photographic, optical materials, and specialty chemical sectors for developing novel imaging agents and light-sensitive materials.

Application

• Sensitizing Dye Intermediate: A key building block for the synthesis of cyanine and related dyes used in silver halide photographic films and papers.
• Optical Recording Media: Used in research for developing materials for optical data storage (e.g., CD-R, DVD-R) due to its light-absorbing properties.
• Laser Dye Precursor: Serves as a starting material for synthesizing near-infrared (NIR) absorbing dyes for laser applications and medical diagnostics.
• Non-Linear Optical Materials: Investigated for use in the development of materials for photonics and electro-optical devices.
• Biomedical Imaging Probes: Utilized in research to create fluorescent or photoacoustic contrast agents for cellular and molecular imaging.
• Organic Semiconductor Research: Acts as a functional component in the development of organic light-emitting diodes (OLEDs) and photovoltaic cells.

Quality Control

Our production of this specialty chemical adheres to strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance with your research or manufacturing 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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and opened under controlled conditions to minimize exposure to atmospheric moisture and light.
