Manufacturing Quality Control of 2,4-Difluoro-5-nitrophenol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~260 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-DAD or UPLC-MS | Separation and identification of impurities (e.g., isomers, residual starting materials, degradation products) using gradient elution and spectral/mass confirmation. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., dichloromethane, acetone, methanol) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with sample moisture. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, offering sub-ppt detection limits per ICH Q3D. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions leached from synthesis residues or reagents. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate (pharmacopeial method). |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of crystalline form and quantitative color measurement in solution against platinum-cobalt standards. |
| Residue on Ignition | Gravimetric Analysis | Mass loss upon high-temperature ashing (700–800 °C) to determine inorganic residue content. |
| pH (1% w/v aqueous suspension) | pH Meter with Combination Electrode | Measurement of surface proton activity in aqueous suspension, indicating acidic phenolic character and potential hydrolysis. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values relevant to handling and formulation performance. |
