Manufacturing Quality Control of CASHMERAN
| Test Item | Common Testing Methods | Method Description |
|---|---|---|
| Appearance | Visual inspection, Melting point determination | Observe sample color and form (usually white or off-white crystalline powder), and determine melting point range (~130–135°C) to confirm purity. |
| Identification | UV-Visible Spectrophotometry (UV-Vis) | Determine absorption peaks at specific wavelengths (e.g., 254 nm), compare absorption spectra with reference standards to confirm structural characteristics. |
| Identification | High Performance Liquid Chromatography (HPLC) | Use C18 column with mobile phase of methanol-water or buffer system. Qualitative identification by comparing retention time with reference standards. |
| Identification | Infrared Spectroscopy (IR) | Determine infrared absorption spectrum and compare with standard spectra for characteristic functional group absorption peaks (e.g., benzene ring, piperidine ring, thione group, etc.). |
| Content Determination | High Performance Liquid Chromatography (HPLC) | Quantification using external standard or internal standard method; detection wavelength 254 nm; typical linear range 1–100 μg/mL; R² > 0.999; precision RSD < 2%. |
| Content Determination | Non-aqueous Titration | Peracetic acid titrant in acetic acid medium with crystal violet as indicator; suitable for raw material drug content determination (pharmacopoeia method). |
| Impurity Test | High Performance Liquid Chromatography (HPLC) | Gradient elution method for related substances; set impurity limit (e.g., total impurities ≤ 1.0%); resolution between main peak and impurities > 1.5. |
| Solvent Residue | Gas Chromatography (GC) | Using headspace injection or direct injection to detect residual solvents such as ethanol, acetone, dichloromethane, complying with ICH Q3C standards. |
| Water Content | Karl Fischer Titration | Determine water content using coulometric or volumetric methods; controlled to ≤ 0.5% (depending on dosage form requirements). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Furnace digestion followed by dissolution, then measure heavy metals like lead, arsenic, cadmium, mercury according to pharmacopoeia limits (e.g., ≤ 10 ppm). |
| Dissolution (for formulations) | Dissolution Apparatus + HPLC | For tablets or capsules, use paddle or basket method under simulated gastrointestinal conditions to measure dissolution percentage within a specified time (e.g., ≥ 80%). |
| Crystal Form (if applicable) | X-ray Powder Diffraction (XRPD) | Used to confirm consistency of raw material crystal form to prevent impact on dissolution and stability due to polymorphic transformation. |
