Manufacturing Quality Control of 2-Chloro-4-fluorobenzoyl chloride
| 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. |
| 2-Chloro-4-fluorobenzoic Acid (Hydrolysis Impurity) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on a reversed-phase C18 column; quantification by UV absorbance at 230–254 nm relative to a calibration curve. |
| Residual Solvents (e.g., Toluene, DCM) | Headspace Gas Chromatography (HS-GC) with FID or MS detection | Volatile solvents partitioned into headspace and analyzed via GC; quantified against external/internal standards. |
| Acid Value (Free HCl / Hydrolyzable Chloride) | Potentiometric Acid-Base Titration | Titration with standardized NaOH solution using potentiometric endpoint detection to quantify acidic impurities from hydrolysis. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical titration where iodine is generated in situ; water reacts stoichiometrically with iodine, enabling precise trace moisture quantification. |
| Heavy Metals (Pb, Cd, Cr, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Sample digestion followed by elemental ion detection and quantification based on isotopic mass-to-charge ratios and calibration standards. |
| Appearance & Color | Visual Inspection against Platinum-Cobalt (Pt-Co) Scale | Comparison of sample clarity and yellowish tint to standardized Pt-Co color solutions under controlled lighting. |
| Density | Oscillating U-tube Density Meter | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with the liquid. |
| Refractive Index | Digital Refractometer | Determination of refractive index at 20 °C by measuring the critical angle of total internal reflection. |
| Chloride Ion (Inorganic Chloride) | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column; quantitative detection of Cl⁻ based on electrical conductivity response. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Ignition of dried sample at 700–800 °C; residue weight measured after cooling in desiccator to determine inorganic ash content. |
| Boiling Point / Distillation Range | Microscale Vacuum Distillation with Digital Thermometry | Determination of boiling behavior under reduced pressure using calibrated temperature sensors and controlled vacuum. |
| Odor | Sensory Evaluation (Trained Panel) | Qualitative assessment by trained personnel for characteristic pungent acrid odor consistent with acid chloride functionality. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at specified wavelength (e.g., 589 nm) and temperature to detect chiral impurities (if applicable). |
