Manufacturing Quality Control of 2-(P-TOLUENESULFONYL)ACETOPHENONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., unreacted benzoyl chloride, p-toluenesulfonyl chloride, desulfonylated byproducts) via gradient HPLC-UV. |
| Residual Solvents | GC-FID | Measures residual solvents (e.g., dichloromethane, toluene, acetone) using gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Quantifies trace metals (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration under controlled lighting against standard criteria. |
| Acid Value | Acid-Base Titration | Determines free acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying at specified temperature (e.g., 105 C) for fixed time under vacuum or air. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after high-temperature ignition following sulfuric acid treatment. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity (if applicable) and detect racemization or contamination. |
