Manufacturing Quality Control of DL-CAMPHORQUINONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of camphorquinone and compare it with standard spectra to confirm the presence of characteristic functional groups (such as carbonyl groups). |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Use the characteristic absorption peak of camphorquinone at specific wavelengths (e.g., approximately 280–330 nm) for qualitative identification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (typically at 254 nm or 320 nm) for quantitative analysis of camphorquinone content. It offers high sensitivity and good reproducibility. |
| Gas Chromatography (GC) | Applicable for camphorquinone samples with better volatility, often combined with an FID detector for quantification. However, attention should be paid to its thermal stability. | |
| Related Substances/Impurity Check | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution programs to separate and detect possible synthetic by-products or degradation products in camphorquinone. Impurity content can be calculated using area normalization or reference substance methods. |
| Melting Point | Melting Point Determination Method | Measure the melting temperature range using a melting point apparatus (literature value is approximately 79–81 °C), serving as an auxiliary indicator for purity assessment. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Pressure Drying Method | Dry at a specified temperature (e.g., 105 °C) until constant weight is achieved, and measure the mass loss to evaluate the water content and volatile components. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection, combined with FID or MS detectors, to determine residual organic solvents (such as acetone, ethanol, etc.) from the production process. |
| Appearance and Color | Visual Colorimetry | Observe the sample color (usually white to pale yellow crystalline powder) under natural light or standard light source to judge whether it meets the standard requirements. |
