Manufacturing Quality Control of 6-Bromoisatinic anhydride
| 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-DAD | Separation and identification of impurities by HPLC coupled with diode array detection; impurities quantified relative to main peak using response factors. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., dichloromethane, acetone) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after incineration at 700-800 C, expressed as percentage of sample mass. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after mechanical tapping of a known mass in a graduated cylinder, per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, used to assess chiral purity and identity. |
