Description

2-Thiophenecarboxaldehyde, 5-[2,5-bis(2-butyloctyl)-2,3,5,6-tetrahydro-3,6-dioxo-4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-thienyl]pyrrolo[3,4-c]pyrrol-1-yl]- is a high-value, multifunctional organic compound featuring a complex molecular architecture that integrates thiophene, pyrrolopyrrole, and boronic ester functionalities. This compound matters as a critical advanced organic intermediate for the synthesis of novel materials, particularly in the development of next-generation electronic and optoelectronic devices. It is primarily needed by R&D chemists and process engineers in the organic electronics, semiconductor materials, and pharmaceutical research sectors, where its unique structure enables the creation of polymers and small molecules with tailored properties.

Application

• Organic Semiconductor Synthesis: A key building block for donor-acceptor type conjugated polymers and small molecules used in Organic Field-Effect Transistors (OFETs) and Organic Photovoltaics (OPVs).
• OLED Material Development: Serves as a precursor for emissive or charge-transport layers in Organic Light-Emitting Diodes (OLEDs) due to the electron-deficient pyrrolopyrrole-dione unit.
• Suzuki-Miyaura Cross-Coupling Reactions: The pinacol boronate ester group makes it an excellent partner for palladium-catalyzed cross-coupling, enabling precise construction of complex π-conjugated systems.
• Non-Fullerene Acceptor (NFA) Development: Used in the research and production of high-performance NFAs for bulk-heterojunction solar cells.
• Chemical Sensor Fabrication: The integrated thiophene and receptor units make it suitable for developing selective chemosensors.
• Pharmaceutical Research Intermediate: Potential use in medicinal chemistry for creating novel heterocyclic compounds with biological activity.

Quality Control

Our 2-Thiophenecarboxaldehyde derivative is produced under stringent conditions to ensure batch-to-batch consistency critical for advanced material synthesis. Quality is verified through a comprehensive suite of analytical techniques including HPLC, NMR (1H and 13C), and Mass Spectrometry to confirm identity, purity, and the integrity of the boronic ester group. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. This compound is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
