N-Iodosuccinimide (NIS, CAS 516-12-1) is a mild, high-efficiency electrophilic iodinating reagent for fine organic synthesis. Our product is 99% purity, white crystalline powder, with good solubility and stable iodine release characteristic.

NIS is preferred for selective iodination of ketones, aldehydes, aromatic rings and glycoside modification. It is extensively used in biopharmaceutical intermediate development, carbohydrate chemistry, peptide labeling and advanced material research. It works under mild conditions with less side reaction than elemental iodine.

We support small trial order and large-volume supply. SDS, COA and handling guidance are ready for compliance.
