Manufacturing Quality Control of 5-Methylpyridine-2,3-dicarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities by gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on retention time and peak area calibration. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic mass spectrometry for ultra-trace sensitivity. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via external calibration curve. |
| Sulfate Content | Ion Chromatography | Separation and conductivity detection of sulfate ions in aqueous extract; quantified via external calibration curve. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content by stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to assess inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity consistency. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic character. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after standardized tapping to evaluate powder flow and handling properties. |
