Nitrofurantoin (Furadantine), an antibiotic, inhibits bacterial DNA, RNA, and cell wall protein synthesis. Activated by bacterial flavoproteins to intermediates that inactivate bacterial ribosomal proteins, Nitrofurantoin is used prophylactically as a urinary anti-infective agent against most gram-positive and gram-negative organisms and for long-term suppression of infections.

Nitrofurantoin-13C3 is intended for use as an internal standard for the quantification of nitrofurantoin by GC- or LC-MS. Nitrofurantoin (T1313) is a nitrofuran antibiotic.1

Nitrofurantoin Sodium is a sodium salt form of nitrofurantoin, a synthetic derivative of imidazolidinedione (hydantoin) that inhibits bacterial DNA, RNA, and cell wall protein synthesis.
