GFS Chemicals maintains a proud tradition in iodine chemistries and iodine compounds . Our iodides, iodates, and periodates have established a worldwide reputation for high quality and high purity. These are used in everything from weather modification to organic catalysts to analytical chemistry; to name only a few of their uses. GFS has recently ventured into other aspects of iodine chemistry - iodine (iodonium) cations being one representative example. Our well-established iodine feedstock supply chains guarantee that our prices will be comparable to those of our competition.
