Manufacturing Quality Control of 1829-40-9
| 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. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction specific to water. |
| Heavy Metals (as Pb) | ICP-OES | Measures total heavy metal content after acid digestion by inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Acid Value | Acid-Base Titration | Measures acidic impurities by titration with standardized KOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing of the cooled crucible. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation of scattered laser light. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or degradation products in solution. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Quantifies mass loss upon controlled heating to determine volatile content including low-boiling impurities. |
