Description

2-[2-[4-[(2-Cyanoethyl)Methylamino]Phenyl]Vinyl]-1,3,3-Trimethyl-3H-Indolium Acetate CAS NO 65122-06-7 is a specialized cationic cyanine dye intermediate with significant commercial and research value. Its core utility lies in its ability to act as a key precursor for synthesizing near-infrared (NIR) fluorescent dyes and photosensitizers. This compound is essential for manufacturers and R&D laboratories in the photographic, optical data storage, biomedical imaging, and photodynamic therapy sectors, where precise light absorption and emission properties are critical.

Application

• Synthesis of NIR Cyanine Dyes: Primary use as a building block for creating heptamethine and other polymethine cyanine dyes used in bio-labeling and fluorescence imaging.
• Optical Data Storage Media: A key material in the formulation of recordable CD-R and DVD-R dyes, where its spectral properties are tuned for specific laser wavelengths.
• Biomedical Imaging Probes: Used to develop contrast agents and fluorescent tags for in vivo and in vitro diagnostic applications, including tumor targeting.
• Photodynamic Therapy (PDT): Serves as a precursor for photosensitizers that generate reactive oxygen species upon light activation for targeted cancer treatment.
• Laser and Nonlinear Optical Materials: Incorporated into organic compounds for their high molar absorptivity and potential use in laser dyes and optical limiters.
• Analytical Chemistry Reagents: Utilized in the development of sensitive fluorescent sensors and indicators for metal ion detection and other analytes.

Quality Control

Our production of 2-[2-[4-[(2-Cyanoethyl)Methylamino]Phenyl]Vinyl]-1,3,3-Trimethyl-3H-Indolium Acetate adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and meet the exacting standards required for advanced optical applications. Certificates of Analysis (COA) detailing purity, spectral data, and impurity profiles are provided with each shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and performance. Keep away from incompatible materials.
