Manufacturing Quality Control of 6-Fluoro-2-oxindole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV/DAD | Separation and identification of structurally related impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC with diode-array detection. |
| Residual Solvents | GC-FID | Qualitative and quantitative analysis of volatile organic solvents (e.g., DMF, dichloromethane, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Ni, As) after acid digestion, based on mass-to-charge ratio detection with high sensitivity and selectivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (700–800 °C), expressed as percentage weight loss. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary apparatus per USP <741>. |
| Chloride Impurity | Ion Chromatography (IC) | Quantitative separation and detection of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder size distribution based on angular scattering intensity of laser light. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per Ph. Eur. 2.6.12. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Quantification of volatile content (e.g., solvent, moisture) by measuring mass loss upon controlled heating (105 °C, 2 h) per USP <731>. |
