Description

4,4'-(Benzo[C][1,2,5]Thiadiazole-4,7-Diyl)Dianiline is a high-purity organic intermediate featuring a benzothiadiazole core symmetrically functionalized with aniline groups. This compound matters for its role as a critical building block in the synthesis of advanced functional materials, particularly those requiring electron-deficient aromatic systems. Industrial researchers and manufacturers in the organic electronics and specialty polymer sectors need this material to develop high-performance organic semiconductors, photovoltaic materials, and light-emitting components.

Application

• Key monomer for synthesizing conjugated polymers used in Organic Photovoltaics (OPVs) and Perovskite Solar Cells.
• Building block for Organic Light-Emitting Diodes (OLEDs) and Organic Field-Effect Transistors (OFETs).
• Precursor for dyes and pigments with specific optoelectronic properties.
• Intermediate in the development of non-linear optical (NLO) materials and sensors.
• Research and development of novel electron-transport materials (ETMs).
• Used in academic and industrial R&D for exploring new organic electronic architectures.

Quality Control

Our 4,4'-(Benzo[C][1,2,5]Thiadiazole-4,7-Diyl)Dianiline is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive electronic applications. Each lot is characterized by advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
