Manufacturing Quality Control of 2,3-Difluoronitrobenzene
| 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. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic solvents by equilibrium partitioning into headspace gas followed by GC analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl solution while monitoring pH change to determine total acidic or basic impurity content. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metal ions in argon plasma; quantification via element-specific emission line intensities. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column followed by quantitative detection based on electrical conductivity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 700-800 C in a platinum crucible; residue mass measured after cooling to determine inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or optically as solid-to-liquid phase change; determined per USP <741>. |
| Color | APHA Color Scale (Visual Comparison or Spectrophotometric) | Comparison of sample solution color intensity against platinum-cobalt standards or measurement of absorbance at 455 nm. |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Solvent evaporation under controlled conditions followed by weighing of residual material on pre-tared dish. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral impurity or enantiomeric excess. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation of structurally similar compounds on reversed-phase column; detection and quantification at 254 nm using external standard calibration. |
