| Organic Synthesis | Fluorinated aromatic acid chloride reagent for constructing complex molecular frameworks | Acylation donor in transition metal-catalyzed reactions, including Friedel–Crafts acylation and Suzuki coupling |
Manufacturing Quality Control of 2,4-Difluorobenzoyl chloride
| 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 | Volatile impurities are vaporized in sealed vials and quantified by GC-FID or GC-MS against calibrated standards. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities (e.g., residual HCl, benzoic acid) with standardized sodium hydroxide using phenolphthalein indicator. |
| Color | Visual Comparison (APHA/Pt-Co scale) | Sample color is assessed in a 100-mm cell against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measures sample density via frequency shift of an oscillating U-shaped glass tube filled with the liquid. |
| Refractive Index at 20 C | Digital Refractometer | Determines refractive index by measuring critical angle of total internal reflection at the prism-sample interface. |
| Chloride Ion (as HCl) | Ion Chromatography (IC) with conductivity detection | Separation of chloride ions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Heavy Metals (Pb, Cd, Cr, Hg, As) | ICP-OES after microwave-assisted acid digestion | Multi-element quantification by plasma excitation emission spectroscopy following complete sample mineralization. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Residue mass determined after evaporation of a known sample volume to dryness at 105 C and constant weight measurement. |
| Aldehyde Impurities (e.g., 2,4-difluorobenzaldehyde) | GC-MS with derivatization (DNPH) | Aldehydes converted to hydrazones using 2,4-dinitrophenylhydrazine, then separated and identified by mass spectral fragmentation. |
| Residual Catalyst (e.g., Fe, Cu) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measures ground-state metal atom absorption of element-specific hollow cathode lamp radiation. |
