Manufacturing Quality Control of BOC-D-ASP-OTBU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 260-280 nm based on peak area comparison with reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., unreacted bromouracil, hydrolysis products) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water content via volumetric or coulometric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-OES | Quantifies total heavy metal content (Pb, Cd, Hg, As, Ni) after acid digestion by inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures optical activity in solution using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine volume-based particle size distribution (D10, D50, D90). |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder under standardized tapping conditions per USP <616>. |
| Microbial Limits | Membrane Filtration | Assesses aerobic microbial count and absence of specified pathogens (E. coli, Salmonella) using culture-based membrane filtration and incubation. |
