Manufacturing Quality Control of DL-Pantolactone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification by retention time matching and peak area normalization. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue as sulfate ash. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Sulfate | Turbidimetry | Precipitation of sulfate as barium sulfate followed by measurement of turbidity proportional to sulfate concentration. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours, reflecting volatile and moisture content. |
| Specific Absorbance (UV) | UV-Vis Spectrophotometry | Absorbance measurement at specified wavelength (e.g., 210 nm) in ethanol solution to assess chromophore integrity and absence of UV-absorbing impurities. |
