Manufacturing Quality Control of N-BROMOPHTHALIMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NBS content) | Acid-base titration with NaOH | Hydrolysis of NBS releases HBr, which is titrated with standardized NaOH using phenolphthalein indicator. |
| Moisture content | Karl Fischer titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium, measured coulometrically or volumetrically. |
| Residue on ignition | Gravimetric analysis | Sample is ignited at 550-600 C to oxidize organic matter; inorganic residue is weighed after cooling. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-OES | Digestion followed by multi-element quantification via atomic emission from plasma-excited atoms/ions. |
| Chloride impurity | Potentiometric titration with AgNO3 | Chloride ions react with silver nitrate to form AgCl precipitate; endpoint detected by silver electrode potential change. |
| Bromide impurity | Ion chromatography (IC) | Separation of bromide anions on anion-exchange column with conductivity detection. |
| Organic impurities (e.g., phthalimide, N-chlorophthalimide) | HPLC-UV | Separation on reversed-phase C18 column with UV detection at 254 nm; quantified against reference standards. |
| Melting point | Capillary melting point apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Particle size distribution | Laser diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution based on Mie theory. |
| Bulk density | ASTM D1895 method A | Mass of material freely poured into a calibrated cylinder; density calculated from mass/volume ratio. |
| pH of aqueous suspension | pH meter measurement | Aqueous slurry (1:10 w/v) equilibrated and measured with calibrated pH electrode. |
| Stability (decomposition products) | GC-MS | Thermal desorption or solvent extraction followed by separation and identification of volatile decomposition compounds. |
