Manufacturing Quality Control of 5-bromo-2-methylsulfanyl-3H-pyrimidin-4-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) after acid digestion by measuring elemental ion signals in an inductively coupled plasma mass spectrometer. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection following aqueous extraction. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column with suppressed conductivity detection after sample dissolution and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and subsequent weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior observation. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution, used to confirm stereochemical integrity and enantiomeric purity. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dry or wet dispersion by measuring angular variation in intensity of scattered laser light. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder in a standardized cylinder after controlled tapping, reflecting flowability and packing characteristics. |
