Manufacturing Quality Control of 4-Chloro-3-methylaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution with UV absorbance at 254 nm. |
| Moisture Content | Karl Fischer Titration | Volumetric titration using iodine generated in situ to react stoichiometrically with water in the sample dissolved in methanol/pyridine solvent. |
| Residue on Ignition | Gravimetric Analysis | Heating the sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percent of original mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using air-acetylene flame and measurement at characteristic absorption wavelength. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with standardized silver nitrate solution using silver indicator electrode to detect endpoint via potential change. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against standard white background under controlled lighting. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of hydrogen ion activity in a saturated aqueous suspension prepared under defined conditions (e.g., 10% w/v, 25 C). |
| Organic Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantification of residual solvents and low-boiling impurities using electron ionization and spectral library matching. |
| Sulfated Ash | Gravimetric Analysis | Incineration of sample with sulfuric acid followed by ignition at 700 C and weighing of residual inorganic sulfate salts. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after mechanical tapping of a known mass in a calibrated cylinder according to USP <616>. |
