Description

4-Iodo-1-Butanesulfonic Acid Sodium Salt is a versatile organoiodine compound that serves as a key building block and sulfonation reagent in advanced chemical synthesis. Its value lies in its ability to introduce both a sulfonate group and an iodine atom, enabling precise molecular modifications and the creation of functional materials. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for complex synthetic pathways.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of sulfonamide-based drugs and diagnostic agents.
• Agrochemical Synthesis: Serves as a precursor for creating novel herbicides, fungicides, and plant growth regulators with enhanced activity.
• Polymer Modification: Employed to introduce sulfonate and iodine functional groups into polymers, altering solubility, hydrophilicity, and reactivity for specialty materials.
• Ligand and Catalyst Preparation: Utilized in the preparation of specialized ligands for transition metal catalysis and in organometallic chemistry.
• Surface Active Agent Research: Acts as a starting material for synthesizing novel anionic surfactants and emulsifiers with specific chain lengths.
• Chemical Biology & Proteomics: Functions as a bioconjugation reagent or a probe for labeling biomolecules due to its reactive iodine moiety.
• Electrolyte Additive: Investigated for use in battery electrolyte formulations to improve stability and performance.
• Organic Synthesis Building Block: A versatile reagent for nucleophilic substitution and cross-coupling reactions (e.g., Suzuki, Heck) to construct complex organic molecules.
