Quality Standards of Pharmaceutical Grade Nitrofurazone (CP Edition)

According to the Chinese Pharmacopoeia 2020 Edition, nitrofurazone must meet the following quality control requirements:

- Appearance: Yellow or orange-yellow crystalline powder, free from visible impurities upon visual inspection.

- Identification: Confirmation of characteristic functional groups and chemical structure via ultraviolet absorption spectroscopy or infrared spectroscopy.

- Assay: Nitrofurazone content must not be less than 98.0%.

- Clarity and Color of Solution: Prepared aqueous solution should show no significant turbidity or abnormal color.

- Melting Point Range: Should be between 240°C and 244°C.

- Heavy Metal Limit: Must not exceed 20 ppm to ensure drug safety.

- Impurity Testing: Related impurities must be controlled via thin-layer chromatography or high-performance liquid chromatography (HPLC) to ensure purity.

- Loss on Drying: Total moisture and volatile substances must not exceed 0.5%.

- Acidity or Alkalinity: The pH of the prepared solution must fall within the pharmacopoeia-specified range (typically 5.5-7.5).

Medicinal Functions and Applications of Nitrofurazone

As a pharmaceutical raw material, the main uses of nitrofurazone include the following aspects:
