Manufacturing Quality Control of PHENYL P-TOLYL SULFONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Color | Visual Comparison Against APHA Scale | Compares solution color intensity to standardized platinum-cobalt reference solutions. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by atomic absorption at element-specific wavelengths. |
| Sulfate Impurity | Barium Chloride Precipitation | Forms insoluble BaSO4 precipitate from sulfate ions; quantified gravimetrically. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride via argentometric titration using silver nitrate and a silver electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents or volatile organic impurities using flame ionization detection. |
| Iron Content | 1,10-Phenanthroline UV-Vis Spectrophotometry | Forms colored complex with Fe2+; absorbance measured at ~510 nm for quantification. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of saturated aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of scattered laser light. |
