Manufacturing Quality Control of 7-NITROISATIN
| 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 to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection, with peak purity assessment and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content by stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-750 C followed by dissolution of residue in dilute HCl and gravimetric determination of non-volatile inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus, observing onset and clear point under controlled heating rate. |
| Particle Size Distribution | Laser Diffraction | Analysis of dispersed solid particles in liquid medium via light scattering pattern to derive volume-based size distribution. |
| Bulk Density | USP <616> Method I | Measurement of mass per unit volume for freely settled powder in a standardized cylinder under defined conditions. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured upon heating at 105 C for 2 hours, reflecting volatile matter including residual moisture and low-boiling impurities. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of structurally undefined volatile organics using gas chromatography coupled with mass spectrometry and library matching. |
