Manufacturing Quality Control of N-PHENYL-4-BIPHENYLAMINE
| 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 using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., toluene, methanol) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element analysis after acid digestion; detection based on characteristic atomic emission spectra intensities of metals such as Pb, Cd, Hg, As. |
| Chloride Content | Ion Chromatography | Separation of chloride anions on anion-exchange column with conductivity detection; quantified using external calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Sample incinerated at 700-800 C in presence of sulfuric acid; residue weighed after cooling to determine inorganic impurity content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase changes to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and homogeneity under controlled white light against defined reference standards (e.g., white to off-white crystalline powder). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to calculate volume-based particle size distribution in dry or wet dispersion mode. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined by measuring volume of a known mass after standardized tapping (ASTM D1895). |
| Organic Volatile Impurities (OVI) | GC-MS | Screening and semi-quantitative identification of unknown volatile organics using mass spectral library matching and selected ion monitoring. |
