Description

6-Bromo-2-[4-(Diethylamino)Phenyl]-1-Ethylbenz[Cd]Indolium Hydrogen Sulphate is a specialized cationic dye intermediate belonging to the benz[c,d]indolium (cyanine) class, valued for its distinct photophysical properties. This compound is critical for the synthesis of advanced functional dyes and pigments used in high-technology applications. It is primarily sought by manufacturers in the optical materials, laser dyes, and non-linear optics (NLO) sectors, as well as researchers developing novel bio-imaging probes and sensitizers for photovoltaic cells.

Application

• Laser Dye Intermediate: A key precursor for synthesizing near-infrared (NIR) absorbing and emitting cyanine dyes used in tunable dye lasers and optical amplifiers.
• Non-Linear Optical (NLO) Materials: Serves as a building block for organic chromophores with high molecular hyperpolarizability, essential for electro-optic modulators and frequency conversion devices.
• Bio-imaging & Sensing Probes: Used in the development of fluorescent labels and probes for cellular imaging, DNA detection, and diagnostic assays due to its modifiable structure.
• Photovoltaic Sensitizers: Investigated as a potential component in the design of sensitizers for dye-sensitized solar cells (DSSCs) to enhance light absorption.
• Optical Data Storage: A candidate material for use in write-once or rewritable optical recording media due to its light-sensitive properties.
• Specialty Pigments & Inks: Employed in the formulation of high-performance pigments and security inks that require specific spectral characteristics.

Quality Control

Our production of this advanced intermediate adheres to strict quality management protocols, ensuring batch-to-batch consistency critical for optical and electronic applications. Identity and purity are verified using advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and spectral data is provided with each shipment to support your R&D and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under anhydrous conditions. For long-term storage, consider using a desiccant in the storage environment.
