Manufacturing Quality Control of 4,5-DIFLUORO-2-NITROTOLUENE
| 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 | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvents are extracted into headspace and quantified via calibrated GC-FID response. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via conductivity. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Element-specific detection after acid digestion and plasma ionization, offering sub-trace sensitivity. |
| Sulfated Ash | Gravimetric Analysis (Ignition at 550 C) | Sample is charred, sulfated with sulfuric acid, and ignited; residue weight reflects inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection (in glass vial under controlled lighting) | Assessment of physical state, color, and presence of particulates or cloudiness against established visual standards. |
| Acid Value | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities with standardized sodium hydroxide solution; endpoint detected by color change. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700 C) | Weight of non-volatile residue after high-temperature ignition following specified USP/EP procedure. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and wavelength. |
