Manufacturing Quality Control of Bis(4-biphenylyl)amine
| 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, THF) based on calibrated external standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on element-specific atomic emission intensities. |
| Chlorinated Impurities | GC-ECD | Detection and quantification of chlorinated by-products using electron capture detection due to high sensitivity for halogenated compounds. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard references under controlled lighting conditions. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue determined after high-temperature ashing and cooling in a desiccator. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH ethanol solution using phenolphthalein indicator. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined after controlled tapping of a known mass in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns from dispersed particles to calculate size distribution based on Mie theory. |
