For procurement managers and R&D scientists in the chemical industry, identifying reliable sources for high-quality intermediates is paramount. One such crucial compound is 2-Iodothiophene (CAS: 3437-95-4), a versatile building block with extensive applications in organic synthesis, material science, and pharmaceutical development. Understanding its properties, synthesis, and procurement channels can significantly streamline your purchasing process.

What is 2-Iodothiophene?

2-Iodothiophene is an organosulfur compound characterized by a thiophene ring substituted with an iodine atom at the second position. Its molecular formula is C4H3IS, with a molecular weight of approximately 210.04 g/mol. Typically appearing as a yellow to brown or dark green clear liquid, it possesses a refractive index around 1.65 and a relatively low melting point of -40°C, making it easy to handle in various laboratory conditions. Its boiling point is approximately 182°C at atmospheric pressure.

Synthesis and Purity: Ensuring Quality for Your Needs

The synthesis of 2-Iodothiophene can be achieved through several established methods. One common route involves the reaction of thiophene with iodine and mercuric oxide, as documented in historical Organic Syntheses procedures. More contemporary methods might involve halogen exchange reactions, such as reacting 2-chlorothiophene with sodium iodide in a suitable solvent like acetone/THF, often yielding high purity (≥98.69% by HPLC). When sourcing this chemical, always prioritize suppliers who can provide detailed specifications and certificates of analysis (CoA) to confirm purity and other critical parameters. Knowing the CAS number, 3437-95-4, is essential for accurate product identification and supplier inquiries.
