Manufacturing Quality Control of 3-Amino-5-hydroxypyrazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by retention time and UV response relative to main peak using gradient elution. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent; based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing residual mass after cooling. |
| Heavy Metals | ICP-OES | Quantifies elements like Pb, Cd, Hg, As by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Turbidimetry | Measures sulfate as barium sulfate precipitate formation, quantified by light scattering intensity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode in 1% w/v aqueous suspension. |
| Melting Point | Capillary Melting Point Apparatus | Observes temperature range at which solid transitions to liquid under controlled heating rate. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating at 105 C for 2 hours, indicating volatile and moisture content. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against defined standards under controlled lighting. |
| Bulk Density | USP <616> Tapped Density Method | Determines mass per unit volume after mechanical tapping of a known powder mass in a graduated cylinder. |
