Manufacturing Quality Control of 1,2-BIS(TOSYLOXY)ETHANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 700-800 C, and the non-volatile residue is weighed after cooling in a desiccator. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Titration of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column followed by conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification after acid digestion by measuring element-specific atomic emission intensities. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample solution color to platinum-cobalt standards or measurement of absorbance at 455 nm. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface at 20 C using calibrated Abbe refractometer. |
| Specific Gravity | Digital Density Meter | Determination of density relative to water at 20/20 C via oscillating U-tube principle. |
| Non-Volatile Residue | Gravimetric Evaporation | Evaporation of fixed volume under controlled conditions, followed by drying and weighing of residual solids. |
| Related Substances | HPLC with UV Detection | Separation on reversed-phase C18 column and detection at 220 nm; identification and quantification relative to main peak. |
| Odor | Sensory Evaluation | Assessment by trained personnel against defined odor descriptors and intensity scale per USP <113> guidelines. |
