Manufacturing Quality Control of 4-Methylpyrimidine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-methylpyrimidine peak area relative to a calibrated standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, Hg) by measuring absorbance of ground-state atoms in a flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition with sulfuric acid treatment to convert metals to sulfates. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Acid Value | Acid-Base Titration | Measures free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase column and UV absorbance at 254 nm. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile content loss as weight difference before and after controlled heating under nitrogen or air. |
| Specific Optical Rotation | Polarimetry | Determines optical activity by measuring rotation angle of plane-polarized light passing through a solution of the compound. |
