Manufacturing Quality Control of 3-Fluoro-4-nitrobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate) based on calibrated response factors. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; water reacts stoichiometrically with iodine and sulfur dioxide in methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Digestion followed by multi-element quantification via inductively coupled plasma optical emission spectrometry using characteristic atomic emission lines. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified against calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C after sulfuric acid treatment; residual inorganic ash weighed as sulfate-derived oxides. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid-to-liquid phase change occurs. |
| Appearance | Visual Inspection | Assessment under controlled white light against specified criteria (e.g., white to off-white crystalline powder, free from visible foreign matter). |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode; reflects acidic character due to carboxylic group. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in dispersed dry or wet sample. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution; used to confirm chiral purity if relevant (though compound is achiral, detects chiral contaminants). |
