Manufacturing Quality Control of Antioxidant 1790
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, physical state (e.g., liquid or solid), and presence of impurities or precipitates under natural or white light. |
| Assay (Main Component Purity) | High-Performance Liquid Chromatography (HPLC) | Using a C18 column with acetonitrile/water or methanol/water as the mobile phase, detect the main component with a UV detector (e.g., 280 nm) and quantify using external standard method. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction between water and iodine-sulfur dioxide-pyridine-methanol system; moisture content determined by potentiometric or coulometric endpoint detection. High accuracy, suitable for trace water analysis. |
| Melting Point (if solid) | Melting Point Apparatus | Determine the temperature range from initial melting to complete liquefaction using capillary method or automatic melting point instrument to assess purity. |
| Residue on Ignition (Ash Content) | High-Temperature Incineration (Muffle Furnace) | Ignite sample at 550–600°C until constant weight; calculate ash residue as percentage of original sample mass to evaluate inorganic impurity levels. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine concentrations of heavy metals such as lead, cadmium, mercury, and arsenic using AAS or ICP-MS; ensure compliance with pharmacopoeia or ISO standard limits. |
| Residual Volatile Organic Solvents | Gas Chromatography (GC) | Using headspace injection or solvent extraction combined with FID detector to measure residual solvents like methanol, ethanol, and acetone; comply with ICH Q3C guidelines. |
| pH Value (if solution) | pH Meter Measurement | Measure pH directly using a calibrated pH electrode in aqueous solution or diluted sample, ensuring values fall within specified range (e.g., 5.0–7.0). |
| Antioxidant Activity (Functional Verification) | DPPH Radical Scavenging Assay / FRAP Assay | DPPH method: Measure the sample’s ability to scavenge DPPH radicals via UV-Vis spectroscopy and calculate IC50; FRAP method: Assess ferric ion reducing capacity to reflect total antioxidant power. |
| Solubility | Solubility Test | Shake and let stand in common solvents such as water, ethanol, or acetone; observe dissolution behavior and record saturation solubility for process and formulation reference. |
| Stability (Accelerated Testing) | Accelerated Aging Test + HPLC Monitoring | Store samples at 40°C ± 2°C and 75% RH for 1–3 months; periodically sample and analyze degradation of active ingredient using HPLC to evaluate storage stability. |
