Manufacturing Quality Control of 2,3-Difluoro-4-hydroxybenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, toluene) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni after acid digestion; detection based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anion on an anion-exchange column with suppressed conductivity detection; quantified using external calibration. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-750 C after sulfuric acid treatment; residual inorganic sulfate converted to stable metal sulfates measured by weight. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; determined by controlled heating and visual detection of meniscus collapse. |
| Appearance | Visual Inspection | Assessment of crystalline form, color, and physical homogeneity against established reference standard under controlled white light and specified viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined saturated aqueous suspension (e.g., 1% w/v) using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine volume-based particle size distribution in dispersed slurry. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening of volatile organic impurities using gas chromatography coupled with mass spectrometry for identification and quantification. |
