Manufacturing Quality Control of 4,4'-DIACETOXYBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., monoacetyl derivatives, unreacted biphenyl) using gradient HPLC-UV; identification by retention time matching. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., acetic anhydride, pyridine, toluene) based on calibrated external standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation to determine water content based on stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma emission intensity at element-specific wavelengths. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 750 C followed by sulfuric acid treatment and final ash weighing to determine inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range where solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment under controlled white light against a white background for color, clarity, and presence of visible particulates or discoloration. |
| Bulk Density | Graduated Cylinder Method | Mass of material divided by volume it occupies in a standardized cylinder after controlled tapping. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to derive size distribution based on Mie scattering theory. |
| Organic Volatile Impurities | GC-MS | Identification and semi-quantification of trace volatile organics using mass spectral library matching and selected ion monitoring. |
