Manufacturing Quality Control of 3-Nitro-2-pyridinol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance and Physical Properties | Visual Inspection | Observe the sample's color, physical state (e.g., powder, crystal), presence of lumping or visible impurities. Typically, it should appear as a pale yellow to yellow crystalline powder. |
| Purity and Main Component Content | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase consisting of methanol-water or acetonitrile-water (containing buffer salts such as phosphate). Detect at UV wavelengths between 254–310 nm using a UV detector. Calculate purity and content of the main peak via external standard method or normalization method. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilize ¹H-NMR and ¹³C-NMR to confirm the molecular structure by comparing chemical shifts of hydroxyl groups, nitro groups, and hydrogen/carbons on the pyridine ring with published literature data. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Detect characteristic functional group absorption peaks: e.g., O-H stretching vibration (~3200–3500 cm⁻¹), asymmetric NO₂ stretching (~1530 cm⁻¹), and aromatic C=C skeletal vibrations (~1600, 1500 cm⁻¹). |
| Moisture Content | Karl Fischer Titration | Quantitatively determine water content based on the reaction between iodine and sulfur dioxide in an anhydrous environment. Suitable for trace moisture analysis. |
| Residual Solvents | Gas Chromatography (GC) | Follow ICH guidelines to detect organic solvents potentially remaining from production processes (e.g., methanol, ethanol, acetone, dichloromethane). Use polar or non-polar capillary columns for separation and FID detection. |
| Melting Point | Melting Point Apparatus Method | Determine initial and final melting temperatures using automatic or manual melting point apparatus, used to assess substance purity and consistency. |
| Related Substances (Impurities) | HPLC (Gradient Elution) | Optimize gradient elution program to separate the main component from potential synthesis intermediates or degradation products. Calculate areas of impurity peaks and report their relative percentages. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, detect residual heavy metals such as lead, cadmium, mercury, and arsenic. Results must comply with pharmacopoeial or relevant safety standards. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Incinerate the sample at high temperature, then treat with sulfuric acid, followed by weighing the residual inorganic matter to assess inorganic impurity levels. |
