Description

4,5-Dibromothiophene-2-Carboxaldehyde is a high-purity, multi-functional brominated thiophene derivative serving as a critical building block in advanced organic synthesis. Its value lies in its dual bromine substituents and reactive aldehyde group, which enable precise and efficient construction of complex heterocyclic systems. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, anti-infectives, and oncology.
• Agrochemical Synthesis: Used to construct active molecules for crop protection agents, including fungicides and herbicides, leveraging the thiophene scaffold's bioactivity.
• Organic Electronic Materials: Serves as a monomer or building block for conjugated polymers and small molecules used in Organic Light-Emitting Diodes (OLEDs), Organic Photovoltaics (OPVs), and field-effect transistors (OFETs).
• Ligand and Catalyst Development: The aldehyde functionality allows for the creation of specialized ligands for metal catalysis and coordination chemistry.
• Chemical Research & Development: A versatile reagent for exploring new heterocyclic chemistry, Suzuki-Miyaura cross-coupling reactions, and other palladium-catalyzed transformations.
• Dye and Pigment Intermediate: Used in the synthesis of specialized dyes and pigments where the thiophene core contributes to color and stability properties.

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 after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
