Manufacturing Quality Control of Nicotinamide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilizes the characteristic absorption peak of nicotinamide at a specific wavelength (e.g., around 261 nm) for qualitative identification via UV spectroscopy. |
| Fourier Transform Infrared Spectroscopy (FT-IR) | Measures the infrared absorption spectrum of the sample and compares it with a reference spectrum to confirm whether the functional group structure matches that of nicotinamide. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a C18 column with water-methanol or buffer solution as the mobile phase and a UV detector for quantitative analysis of nicotinamide. Offers high accuracy and strong specificity. |
| Ultraviolet Spectrophotometry | Measures absorbance at the maximum absorption wavelength and calculates content based on a standard curve. Simple to operate but less specific than HPLC. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employs gradient or isocratic elution to separate nicotinamide from its degradation products (e.g., nicotinic acid, by-products), enabling detection and limit control of impurities. |
| Water Content | Karl Fischer Titration | A titration method for precise determination of moisture content in samples; suitable for trace water detection and commonly used in pharmacopoeias. |
| Solution Clarity | Visual Turbidity Comparison | The sample is prepared into a solution of specified concentration and compared visually with a standard turbidity solution to assess clarity, used to control insoluble impurities. |
| Solution Color | Colorimeter or Visual Color Comparison | Compares the solution color with standard color solutions to evaluate whether it falls within acceptable limits, used to control colored impurities. |
| Sulfated Ash | Sulfated Ash Test | The sample is ignited at high temperature and the residue is weighed to determine the total amount of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Sulfide Precipitation Method | AAS enables quantitative determination of heavy metals such as lead and cadmium; the sulfide method is a traditional pharmacopoeial approach that detects total heavy metals through a colorimetric reaction. |
| Microbial Limits | Microbial Limit Test | Includes total aerobic microbial count, mold and yeast count, and testing for specified microorganisms (e.g., *Escherichia coli*) to ensure microbiological safety. |
