Manufacturing Quality Control of 5-Dibenzosuberenone
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectrophotometry (IR) | Confirm characteristic functional groups (e.g., carbonyl C=O strong absorption peak around 1660 cm⁻¹) by comparing the sample's infrared absorption spectrum with a reference spectrum. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze the chemical shifts, coupling constants, and integration areas of hydrogen atoms in the compound to verify molecular structure. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (typically 254 nm) to quantify the main component. |
| Gas Chromatography (GC)* (if applicable) | If the compound has sufficient volatility and thermal stability, GC may be used for assay, although HPLC is more commonly used. | |
| Related Substances (Impurity Check) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from potential impurity peaks using a gradient elution program; assess impurity levels by area normalization or reference substance method. |
| Melting Point | Melting Point Determination | Determine the melting temperature range using a melting point apparatus to assess purity (pure substances usually have a narrow melting range, e.g., 138–140 °C). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105 °C) to constant weight and calculate the percentage weight loss to evaluate moisture and volatile impurities. |
| Residual Solvents | Gas Chromatography with Head-Space Injection (HS-GC) | Detect organic solvents possibly remaining from synthesis or purification processes in accordance with ICH Q3C guidelines (e.g., toluene, dichloromethane). |
| Appearance and Color | Visual Color Comparison Method | Observe the color and physical state of the sample under standard lighting conditions (usually white to off-white crystalline powder) and compare with standard color solutions. |
| UV-Visible Absorption | UV-Visible Spectrophotometry (UV-Vis) | Measure absorbance at specific wavelengths (e.g., 254 nm or maximum absorption wavelength) for identification support or preliminary assay screening. |
