Manufacturing Quality Control of 4-Bromophenylhydrazine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-bromoaniline, bromobenzene, hydrazine derivatives) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., ethanol, acetone, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals (Pb, Cd, Hg, As, Cr) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Ion | Potentiometric Titration | Titration with silver nitrate using a silver/silver chloride electrode to detect endpoint via potential change. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic sulfate ash. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light. |
| pH (1% aqueous solution) | pH Meter Measurement | Measurement of hydrogen ion activity in a freshly prepared aqueous solution using a calibrated pH electrode. |
| Residual Hydrazine | Derivatization HPLC-UV | Reaction with benzaldehyde to form hydrazone derivative, followed by HPLC separation and UV quantification. |
| Bulk Density | USP <616> Tap Density Method | Determination of mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
