Manufacturing Quality Control of 6-NITRO-2H-1,4-BENZOXAZIN-3(4H)-ONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-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, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Multi-element detection of toxic metals (Pb, Cd, Hg, As) after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of residual inorganic salts as sulfate ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate; used for identity and purity assessment. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Mass loss measured upon heating to 105 C under dry nitrogen, indicating volatile content including residual solvents and moisture. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line, confirming chiral integrity if applicable. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode to assess acidic/basic impurities. |
