Manufacturing Quality Control of 1,4-Naphthoquinone
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water; detection is performed using a UV detector at approximately 254 nm, with external standard quantification. This method offers high accuracy and is suitable for purity and active ingredient analysis. |
| Appearance and Physical Properties | Visual Inspection | Observes the sample's color, physical state (e.g., yellow crystalline powder), presence of clumping or visible impurities, ensuring compliance with pharmacopoeial or corporate specifications. |
| Melting Point | Melting Point Determination (Capillary Method) | Uses a melting point apparatus to determine the melting temperature range (literature value approximately 125–127°C) to preliminarily assess substance purity and consistency. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Uses the same conditions as the assay or optimized gradient elution to detect organic impurities such as synthetic intermediates and oxidation by-products in raw materials; impurity peak areas are calculated and limited according to specified thresholds. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, detects organic solvents potentially residual from manufacturing processes (e.g., methanol, ethanol, acetone), using an FID detector and headspace sampling to enhance sensitivity. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dries the sample to constant weight at a specified temperature (e.g., 105°C) and measures the percentage weight loss to evaluate moisture and volatile component content. |
| Residue on Ignition | Sulfated Ash Method | The sample is carbonized, treated with sulfuric acid, and then incinerated at high temperature; the weight of the inorganic residue is measured to assess inorganic impurity content. |
| Water Content | Karl Fischer Titration | Uses a Karl Fischer titrator to precisely measure bound and free water content in the sample; suitable for trace moisture detection with high accuracy and reliability. |
| Fourier Transform Infrared Spectroscopy (FT-IR) Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Samples are analyzed by pellet pressing or ATR technique to obtain an infrared absorption spectrum, compared with a reference spectrum to confirm characteristic functional group absorptions (e.g., C=O stretching vibration at ~1660 cm⁻¹) for structural verification. |
| Crystal Form Analysis | X-ray Diffraction (XRD) | Analyzes the crystal structure of solid samples to determine the presence of polymorphic forms, ensuring batch-to-batch consistency in physical properties such as stability and solubility. |
