Manufacturing Quality Control of Antioxidant 1098
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 280 nm, comparing peak area to a certified reference standard. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following ASTM D1560 or ISO 4625. |
| Appearance | Visual Inspection | Assessment of physical state and color against a white background under controlled lighting; acceptable as white to light yellow crystalline powder. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying sample at 105 C for 2 hours; reflects volatile content and residual solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue after high-temperature ashing (750 C) followed by sulfuric acid treatment and re-ignition. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of total heavy metals after wet digestion, reported as lead equivalent. |
| Chlorinated Compounds | GC-ECD | Detection and quantification of chlorinated impurities using gas chromatography with electron capture detection. |
| Hydroquinone (Impurity) | HPLC-UV | Separation and quantification of hydroquinone, a potential synthesis intermediate or degradation product, using validated HPLC method. |
| Acid Value | Acid-Base Titration (KOH in ethanol) | Neutralization of acidic impurities with standardized potassium hydroxide solution; expressed as mg KOH/g sample. |
| Ash Content | Gravimetric (Ignition) | Mass of non-volatile residue remaining after ignition at 550 C for 30 minutes in a muffle furnace. |
| Bulk Density | Volumetric Method (ASTM D1895) | Measurement of mass per unit volume of freely settled powder in a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of size distribution based on light scattering patterns of dispersed particles in air or liquid medium. |
