Description

2-Iodobenzenesulfonic Acid Sodium Salt is a versatile organoiodine compound that serves as a key synthetic intermediate and building block in advanced chemical synthesis. Its value lies in the unique reactivity of the iodine substituent, which enables selective cross-coupling reactions and functional group transformations. This high-purity material is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing new active ingredients and complex organic molecules.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring aryl-iodide motifs in Suzuki, Stille, or other palladium-catalyzed cross-coupling reactions.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and pesticides where the introduction of a sulfonate group and iodine atom modifies biological activity and solubility.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands and organometallic catalysts used in homogeneous catalysis.
• Material Science Research: Employed in the development of organic electronic materials, dyes, and photoactive compounds due to its heavy atom effect and potential for further functionalization.
• Chemical Biology Probes: Useful in creating labeled compounds and probes for biochemical and diagnostic research applications.
• Custom Synthesis and Contract Manufacturing: A valuable starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving diverse R&D projects.

Quality Control

Our 2-Iodobenzenesulfonic Acid Sodium Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, residual solvent analysis, and identification by FT-IR and NMR. Certificates of Analysis (COA) detailing all specifications and test results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
