Manufacturing Quality Control of 3-HYDROXY-4-METHYLPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~260 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-methylpyridine, 3-chloro-4-methylpyridine) using gradient HPLC-UV with system suitability criteria per ICH Q2(R2). |
| Residual Solvents | GC-FID | Headspace GC-FID analysis for common solvents (e.g., methanol, acetone, toluene) based on USP <467> or ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation; suitable for low-level moisture quantification in hygroscopic organic solids. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, meeting ICH Q3D elemental impurities limits. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (500–600 °C), per USP <281>. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change; used for identity and purity screening per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of chiral rotation of plane-polarized light; confirms enantiomeric integrity (though compound is achiral, detects chiral contaminants). |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of acidity/basicity in saturated aqueous suspension (1% w/v), indicating residual acidic/basic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion to assess bulk handling and dissolution behavior per ISO 13320. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white-light illumination per USP <1171>. |
