Manufacturing Quality Control of 4-Fluorocatechol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 280 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., mono-fluoro isomers, quinones, residual starting materials) using gradient HPLC with UV monitoring. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, acetone, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after high-temperature incineration (700-800 C) of sample with sulfuric acid treatment, expressed as percentage. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; reported as onset and clear point range per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid material against established reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in dry or dispersed state using Mie scattering theory and optical detection. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Organic Volatile Impurities (OVI) | GC-MS | Confirmatory identification and quantification of low-level volatile organic impurities using mass spectral library matching and selected ion monitoring. |
