Manufacturing Quality Control of 1518-58-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl using bromocresol green indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction with iodine and sulfur dioxide in methanol. |
| Heavy Metals | ICP-OES | Determines trace metal impurities (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in 1% w/v aqueous solution using calibrated pH electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Detects residual solvents (e.g., ethanol, toluene) by capillary GC separation and flame ionization detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated thermal block. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume of freely settled powder in a standardized cylinder. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular scattering pattern of laser light passed through dispersed sample. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity against APHA color standards using spectrophotometer at 430 nm. |
