Manufacturing Quality Control of H-SER(TBU)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Chiral Purity | Chiral HPLC or Chiral GC | Separation of enantiomers on a chiral stationary phase; L-isomer content determined by relative peak area. |
| Water Content | Karl Fischer titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in methanol-based solvent. |
| Residual Solvents | Gas Chromatography (GC) with FID | Volatile organic solvents quantified by retention time and peak area against calibrated standards. |
| Heavy Metals | ICP-OES | Multi-element detection of metallic impurities after acid digestion, based on atomic emission intensity. |
| Chloride Impurity | Ion Chromatography (IC) | Quantitative separation and detection of chloride anions using conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) or Turbidimetry | Sulfate measured either by IC conductivity detection or barium sulfate precipitate formation and light scattering. |
| pH of Aqueous Solution | Potentiometric pH measurement | Hydrogen ion activity determined using calibrated glass electrode in a 1% w/v aqueous suspension. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Mass loss measured after drying at 105 C under vacuum or nitrogen for 2 hours. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of foreign particles against established visual standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm). |
| Microbial Limits | Membrane filtration followed by colony counting | Viable aerobic microorganisms enumerated on tryptic soy agar after filtration and incubation. |
