Description

4-Bromo-7-Methoxybenzo[B]Thiophene is a high-purity, functionalized benzothiophene derivative serving as a critical building block in advanced organic synthesis. This compound matters for its role as a versatile intermediate in the development of complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is needed by R&D chemists and process development scientists working on heterocyclic chemistry, material science, and the synthesis of active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and oncology.
• Agrochemical Synthesis: Used in the research and development of new-generation herbicides and fungicides that leverage the benzothiophene scaffold.
• Material Science Research: Serves as a monomer or functional unit in the development of organic semiconductors, conductive polymers, and advanced organic light-emitting diodes (OLEDs).
• Chemical Research & Development: Employed in cross-coupling reactions (e.g., Suzuki, Stille) and other catalytic transformations to construct complex polycyclic aromatic systems.
• Ligand and Catalyst Development: The bromo and methoxy functional groups make it a useful starting material for synthesizing specialized ligands for metal catalysis.

Quality Control

Our 4-Bromo-7-Methoxybenzo[B]Thiophene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, impurity profiles, and physical data. Our quality commitment supports applications requiring traceability and consistency, from research to scale-up.

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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
