Manufacturing Quality Control of 2,5-DIHYDROXY-1,4-BENZOQUINONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities. Typically appears as yellow to yellowish-brown crystalline powder. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus, used for preliminary assessment of purity and compound consistency. |
| Content/Purity | High-Performance Liquid Chromatography (HPLC) | Employ a reversed-phase C18 column and UV detector (e.g., 254 nm). Quantify the main component using external standard or area normalization methods. Mobile phases typically include methanol-water or acetonitrile-water systems. |
| Structure Confirmation | UV-Visible Spectrophotometry (UV-Vis) | Measure characteristic absorption peaks within the 200–400 nm range (e.g., ~245 nm, ~300 nm shoulder), consistent with a conjugated quinone structure. |
| Structure Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Analyze characteristic absorption peaks of functional groups, such as O-H stretching (~3200–3500 cm⁻¹), C=O (~1660 cm⁻¹), and C=C aromatic ring (~1600, 1500 cm⁻¹). |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H NMR and ¹³C NMR are used to confirm molecular structure, identify aromatic protons, hydroxyl positions, and carbon skeleton. Characteristic signals: aromatic protons around δ 6.3–6.5 ppm. |
| Moisture Content | Karl Fischer Titration | Accurately determine moisture content by titration, applicable for controlling loss on drying and stability evaluation. |
| Related Substances / Impurities | HPLC with Gradient Elution | Check for possible synthetic intermediates, oxidation by-products, or degradation products. Gradient elution is used to improve resolution. |
| Residual Solvents | Gas Chromatography (GC) | If organic solvents (e.g., methanol, ethyl acetate) are used in production, residual levels must be tested according to pharmacopoeia methods. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine residual heavy metals such as lead, arsenic, and mercury to ensure compliance with pharmaceutical or high-purity reagent standards. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight and calculate the percentage weight loss, reflecting volatile impurities or moisture content. |
| Residue on Ignition | Sulfated Ash Method | Weigh the inorganic residue after high-temperature incineration to evaluate inorganic impurity content. |
