USP/EP-grade Furazolidone (CAS 67-45-8), 98–102%, supplied wholesale by Zyntex for licensed human pharmaceutical use only. Nitrofuran API for tablets and oral suspensions; not for food-producing animals. CoA and SDS.
Furazolidone (C8H7N3O5) is a yellow crystalline powder that is very slightly soluble in water. It belongs to the nitrofuran class, together with nitrofurantoin and nitrofurazone.
Pharmaceutical companies in several countries use it in tablets and oral suspensions for intestinal infections. Its use in food-producing animals is prohibited in the EU, the United States and many other countries, and residue testing in food is strict, because nitrofuran residues are of concern for consumer safety. For this reason, Zyntex supplies furazolidone only for licensed human pharmaceutical use and not for animal feed or veterinary products in food-producing animals.
Other APIs for intestinal infections in our range include Metronidazole and Sulfaguanidine.
