Manufacturing Quality Control of 93107-30-3
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of visible foreign particles under natural light or standard illumination. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with a reference standard to confirm consistency in functional groups and molecular structure. |
| High-Performance Liquid Chromatography (HPLC) | Identify by comparing retention times with those of reference standards to ensure consistency of target peaks. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase columns (e.g., C18) and UV detection (around 278 nm), quantifying the main component via external or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurities using gradient or isocratic elution; detect and quantify degradation products or synthetic by-products. Total impurities typically required to be ≤0.5%. |
| Moisture Content | Karl Fischer Titration | Accurately determine moisture content using titration, suitable for trace moisture analysis. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (LOD) | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, calculating the percentage of weight loss to reflect volatile components. |
| Residue on Ignition (Ash Content) | Sulfated Ash Method | After high-temperature incineration, treat residue with sulfuric acid to determine non-volatile inorganic impurities. |
| Heavy Metals | Sulfide Colorimetry or Atomic Absorption Spectroscopy (AAS) | Determine total levels of heavy metals such as lead, cadmium, and mercury via colorimetric reactions or instrumental analysis. Typically limited to ≤20 ppm. |
| Residual Solvents | Gas Chromatography (GC) | Detect organic solvents (e.g., methanol, ethanol, dichloromethane, DMF) potentially remaining from synthesis, complying with ICH Q3C guidelines. |
| Polymorphic Analysis | X-Ray Powder Diffraction (XRD) | Analyze crystal structure to ensure polymorphic consistency, especially critical for quality control of polymorphic drugs. |
| Particle Size Distribution | Laser Particle Size Analysis | Determine particle size and distribution, which affect dissolution behavior and bioavailability; commonly used for raw material control prior to formulation. |
