Manufacturing Quality Control of 1-Bromo-4-(phenylsulfonyl)benzene
| 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 (e.g., starting materials, intermediates, degradation products) using gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., toluene, methanol, ethyl acetate) based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via electrochemical or stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; quantifies Pb, Cd, Hg, As, and other regulated metals by atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700-800 C) and weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the sample against specified criteria (white to off-white crystalline powder, free from visible particulates). |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light through a solution to detect chiral impurities (though compound is achiral, confirms absence of optically active contaminants). |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after controlled tapping of a known mass in a graduated cylinder per USP <616>. |
