Manufacturing Quality Control of N,N-BIS(2-HYDROXYETHYL)-P-TOLUENESULFONAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection; impurities quantified relative to main peak. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., ethanol, THF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution to determine free acidic groups; endpoint detected potentiometrically or by indicator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against water-white standard under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus. |
| Residue on Ignition | Gravimetric Analysis | Mass of inorganic residue remaining after high-temperature ashing at 700-800 C, expressed as percentage of original sample. |
| Bulk Density | Tap Density Measurement | Determined by measuring mass of powder in a graduated cylinder before and after standardized tapping procedure. |
