Manufacturing Quality Control of (S)-1-(4-Nitrophenyl)ethylamine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Measures (S)-enantiomer excess using a chiral stationary phase and UV detection, resolving enantiomers based on differential interaction. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water mass fraction via coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Ion Content | Potentiometric Titration | Measures chloride concentration by titration with silver nitrate using a silver/silver chloride indicator electrode. |
| Residual Inorganic Salts | Ion Chromatography | Separates and quantifies anions (Cl-, NO3-, SO42-) and cations (Na+, K+) using suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against white/black background under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measures degree of plane-polarized light rotation in solution at specified concentration, temperature, and wavelength (e.g., 589 nm). |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by measuring mass loss after drying under specified temperature and vacuum conditions for fixed duration. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a defined aqueous suspension using calibrated glass electrode and reference electrode system. |
