Manufacturing Quality Control of 2,5-DICHLORO-4-FORMYLPYRIDINE
| 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 ~254 nm. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, dechlorinated/by-product analogs) relative to main peak using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., DMF, THF, dichloromethane) based on calibrated external standards. |
| Heavy Metals (Total) | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic detection with high sensitivity and low detection limits. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Direct titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection due to AgCl precipitation. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical generation of iodine in anhydrous medium; water content determined stoichiometrically from coulombs required to maintain iodine concentration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measured as the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Subjective assessment of physical state (crystalline powder) and color intensity compared to platinum-cobalt standard solutions. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue after high-temperature ashing (~750 °C), expressed as percentage of original sample weight. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity (if applicable; typically negligible for this achiral compound). |
