Manufacturing Quality Control of 3,4-DICHLORO-N-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 by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID detection | Volatile organic solvents are partitioned into headspace and quantified using calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection via atomic emission from plasma-excited atoms; quantified using calibration curves. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection based on electrical conductivity. |
| Acid-Base Impurities (Total Acid Number) | Acid-Base Potentiometric Titration | Neutralization of acidic components with standardized KOH solution, monitored by pH electrode endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate per pharmacopeial guidelines. |
| Appearance | Visual Inspection (in glass vial under controlled lighting) | Assessment of physical state, color, and presence of particulates or phase separation against established reference standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample ignited at 700-800 C; residue weight measured after cooling in desiccator to determine inorganic ash content. |
| Bulk Density | USP <616> Tap Density Measurement | Mass per unit volume determined after mechanical tapping of a known mass in a graduated cylinder to achieve reproducible packing. |
