Manufacturing Quality Control of 4,5-DICHLORO-2-NITROTOLUENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| 4,5-Dichloro-2-nitrotoluene Isomer Purity | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structural isomers using reversed-phase C18 column and UV absorbance at 254 nm. |
| Residual Solvents (e.g., toluene, dichloromethane) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent quantification via equilibrium partitioning into headspace followed by GC separation and detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) | Multi-element detection after acid digestion, based on element-specific atomic emission lines. |
| Chloride Impurities (e.g., HCl, Cl⁻) | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column and quantitative detection via electrical conductivity. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via visual observation of solid-to-liquid phase change under controlled heating rate. |
| Appearance & Color | Visual Inspection and APHA Color Scale | Comparison of sample solution (in specified solvent) against platinum-cobalt standards under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content after high-temperature incineration and cooling in desiccator. |
| Organic Volatile Impurities (e.g., nitrobenzene, chlorotoluenes) | GC–MS (Gas Chromatography–Mass Spectrometry) | Separation by GC followed by mass spectral identification and semi-quantitation using selected ion monitoring. |
| Acid Value | Potentiometric Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution; endpoint determined by pH inflection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral impurity presence (though compound is achiral, detects optically active contaminants). |
