Manufacturing Quality Control of N-(biphenyl-4-yl)Naphthalene-2-aMine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching with reference standards or relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, xylene) by gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generated electrochemically in presence of water. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, Cr by inductively coupled plasma optical emission spectrometry after acid digestion and matrix-matched calibration. |
| Chlorinated Impurities | GC-ECD | Detects trace chlorinated compounds (e.g., chlorobiphenyls) using gas chromatography with electron capture detection for high sensitivity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Acid Value | Acid-Base Titration | Measures free acidic impurities by titration with standardized KOH solution in ethanol/isopropanol mixture using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after controlled charring and ashing at 700-800 C, followed by weighing of residual sulfate salts. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory applied to laser diffraction pattern analysis. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume of powder before and after standardized mechanical tapping per USP <616>. |
