Manufacturing Quality Control of 4-TOLUENESULFONYLACETIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active compound by titration with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residual Solvents (e.g., Ethyl Acetate, Methanol) | Gas Chromatography (GC-FID) | Separates and quantifies volatile solvents using capillary column and flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metals by plasma ionization and mass spectrometric quantification at isotopic masses. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate anions using suppressed conductivity detection. |
| Related Substances (Impurity Profile) | HPLC-UV | Separates and detects organic impurities using reversed-phase C18 column and UV absorbance at 220 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or discoloration against standard white background. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Loss on Drying (LOD) | Gravimetric Method | Determines volatile content by weight loss after drying at specified temperature and time under controlled conditions. |
| Residue on Ignition | Sulfated Ash Method | Measures non-volatile inorganic residue after high-temperature ignition following sulfuric acid treatment. |
