Manufacturing Quality Control of 4-BROMO-2-HYDROXYBENZONITRILE
| 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 using HPLC coupled with diode-array detection, with peak purity assessment and relative response factor correction. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents by gas chromatography with flame ionization detection, using headspace sampling and internal standard calibration. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water content based on the stoichiometric reaction between iodine, sulfur dioxide, and water. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of non-volatile inorganic residue as sulfate ash. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles or discoloration against established reference standards under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using a calibrated pH electrode and buffer-standardized meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry or dispersed state using Mie scattering theory applied to laser diffraction patterns. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of structurally undefined volatile organics using gas chromatography coupled with mass spectrometric detection and library matching. |
