Phosphorus Derivatives

We offer a wide range of inorganic phosphorus derivatives, including high purity hypophosphites, high purity hypophosphorus acid and a range of phosphates.
These materials are manufactured at Honeywell’s plant in Seelze, Germany, which is certified against ISO/TS 16949, ISO 9001 and 14001.

These products are utilized in a wide variety of applications covering industrial metalworking and metal finishing industries, polymer catalysis and food and nutrition.

For example, our high purity calcium and magnesium hypophosphites and hypophosphorus acid grades are used as active ingredients in both human and veterinary supplements and veterinary medicines, for the treatment of calcium and phosphorus deficiency in animals, while our manganese hypophosphite is used as an active catalyst in polymer synthesis applications.
