Manufacturing Quality Control of O-METHYLISOUREA SULFATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (O-Methylisourea Sulfate Hydrogen Salt) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH using phenolphthalein indicator; based on neutralization of acidic sulfate hydrogen. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ignition at 700-800 C and weighing residual ash. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Chloride Precipitation | Forms insoluble BaSO4 precipitate from sulfate ions in acidic medium; quantified gravimetrically. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content (Pb equivalent) after acid digestion and flame AAS detection. |
| Iron Impurity | UV-Vis Spectrophotometry | Quantifies Fe2+ complexed with 1,10-phenanthroline at 510 nm using absorbance measurement. |
| pH of Aqueous Solution | Potentiometric Measurement | Determines acidity/basicity of 1% w/v aqueous solution using calibrated pH electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Detects and quantifies residual solvents (e.g., methanol, acetone) using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder via Mie scattering analysis of laser beam passing through dispersed sample. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder in a standardized cylinder. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to soybean-casein digest agar, and colony enumeration after incubation. |
