Description

4,7-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-2,1,3-Benzothiadiazole is a high-purity, functionalized benzothiadiazole derivative featuring two pinacol boronate ester groups, making it a critical advanced intermediate for cross-coupling reactions. This compound matters for its role as a key building block in the synthesis of complex organic electronic materials, enabling precise molecular engineering. It is primarily needed by R&D chemists and process engineers in the organic electronics, pharmaceutical, and agrochemical industries for constructing conjugated polymers, small molecule semiconductors, and other functional materials.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: As a versatile bis-boronic ester monomer for constructing conjugated polymers and small molecules used in Organic Light-Emitting Diodes (OLEDs) and Organic Photovoltaics (OPVs).
• Organic Semiconductor Synthesis: A key precursor for developing electron-accepting or ambipolar materials in field-effect transistors (OFETs) and other electronic devices.
• Pharmaceutical Intermediate: Used in the research and development of novel drug candidates, particularly those requiring complex, conjugated heterocyclic cores.
• Agrochemical Active Ingredient Development: Serves as a building block for creating new molecules with potential biological activity.
• Material Science Research: For the development of novel dyes, sensors, and non-linear optical materials due to its electron-deficient benzothiadiazole core.
• Ligand and Catalyst Design: Can be incorporated into frameworks for creating novel ligands or metal-organic frameworks (MOFs).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and when dispensing to prevent hydrolysis of the boronate ester groups. Keep container tightly sealed when not in use.
