Manufacturing Quality Control of 6-BROMO-2-METHYL-3,4-DIHYDROQUINAZOLIN-4-ONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities (e.g., starting materials, intermediates, degradants) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., DMF, toluene, methanol) based on retention time and flame ionization response. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pd, Ni, Fe) via elemental mass spectrometry after acid digestion and dilution. |
| Water Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine generated electrochemically in presence of water. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash residue after high-temperature incineration (500–600 °C) followed by precise weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and identity/purity. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern of laser light. |
| Chloride Impurity | Ion Chromatography (IC) | Quantifies chloride ions via suppressed conductivity detection after anion exchange separation. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral impurities or enantiomeric excess using plane-polarized light in solution. |
| Microbial Contamination | Membrane Filtration & Culture | Detects viable aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v) using calibrated glass electrode. |
| Bulk Density | Tap Density Analyzer | Determines mass per unit volume after controlled tapping of powder in a graduated cylinder per USP <616>. |
