Manufacturing Quality Control of 2-CHLOROETHYL P-TOLUENESULFONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation titration where chloride ions react with silver nitrate, detected by silver ion-selective electrode endpoint. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by ionization in plasma and mass spectrometric detection at isotopic masses. |
| Sulfate Impurity | Ion Chromatography (IC) with conductivity detection | Separation and quantification of sulfate anions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC with UV detection | Identification and quantification of structurally related impurities using reversed-phase chromatography and UV absorbance at 254 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change in a calibrated capillary tube under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
| Volatile Organic Impurities | Headspace GC-MS | Extraction and identification of low-boiling contaminants via equilibrium headspace sampling followed by mass spectral detection. |
| Appearance and Color | Visual Inspection and Hazen (APHA) Scale | Subjective assessment of physical state and quantitative color evaluation against platinum-cobalt standard solutions. |
