Description

Thiophene, 2-Ethyl-5-Iodo- is a halogenated thiophene derivative, a versatile and valuable building block in advanced organic synthesis. Its molecular structure, featuring both an ethyl and an iodine substituent on the thiophene ring, makes it a critical intermediate for constructing complex molecules with tailored electronic and pharmaceutical properties. This compound is primarily sought by research institutions and industrial R&D departments engaged in developing novel materials, agrochemicals, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel drug candidates, particularly in medicinal chemistry programs targeting central nervous system (CNS) disorders and anti-infective agents.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the thiophene core contributes to biological activity.
• Material Science Research: Acts as a precursor for conducting polymers, organic semiconductors, and non-linear optical (NLO) materials due to the electron-rich thiophene system.
• Ligand and Catalyst Development: Employed in the synthesis of specialized ligands for transition metal catalysis and organometallic chemistry applications.
• Chemical Research & Development: A fundamental building block for exploring new organic reactions and synthesizing complex heterocyclic compounds in academic and industrial labs.

Quality Control

Our Thiophene, 2-Ethyl-5-Iodo- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
