Manufacturing Quality Control of Di-2-pyridylglyoxal
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities by retention time and peak area relative to main peak using gradient elution and UV detection. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under controlled temperature and vacuum to determine volatile content including solvents and moisture. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile material. |
| Heavy Metals | ICP-OES | Quantifies total heavy metal content (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Measures chloride ions via titration with silver nitrate using a silver indicator electrode and endpoint detection by potential change. |
| Sulfated Ash | Gravimetric Analysis | Evaluates inorganic residue after ignition with sulfuric acid treatment to convert metals to sulfates prior to weighing. |
| Water Content | Karl Fischer Titration | Determines trace water by volumetric or coulometric titration using iodine-based reagent and electrochemical endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity based on sharpness and agreement with literature value. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration against established visual standards under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., ethanol, chloroform) by observing clarity and residue after defined agitation and standing time. |
| pH of Aqueous Suspension | pH Meter Measurement | Determines acidity/basicity of a standardized suspension in water using calibrated pH electrode, reflecting acidic impurities or degradation products. |
