Description

3-Thiophenecarbonylbromide(9Ci) is a versatile and highly reactive organobromide building block, essential for advanced organic synthesis. Its core value lies in its ability to introduce the 3-thiophenecarbonyl moiety into target molecules, enabling the construction of complex heterocyclic systems. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) with thiophene-based scaffolds, particularly in central nervous system (CNS) and anti-infective drug discovery.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the thiophene ring contributes to biological activity and selectivity.
• Material Science Precursor: Serves as a monomer or functionalization agent in the production of conductive polymers, organic semiconductors, and non-linear optical (NLO) materials.
• Ligand and Catalyst Development: Employed to synthesize sophisticated ligands for transition metal catalysis and organocatalysts used in asymmetric synthesis.
• Chemical Research & Development: A fundamental reagent for academic and industrial research in heterocyclic chemistry, facilitating the exploration of new chemical spaces and reaction pathways.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of specialized dyes and pigments with unique coloristic and stability properties.

Quality Control

Our 3-Thiophenecarbonylbromide(9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability for your critical syntheses. Each lot undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
