Manufacturing Quality Control of 2-MERCAPTO-4(3H)-QUINAZOLINONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using isotopic detection for high sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Impurity | Ion Chromatography | Determination of sulfate ions via anion-exchange chromatography with conductivity detection following sample dissolution. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after controlled incineration at 700-800 C and weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light in solution to assess chiral purity and identity. |
| pH of Aqueous Suspension | pH Meter | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated electrode per EP 2.2.3. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to derive D10, D50, D90 values. |
