Manufacturing Quality Control of L-NORVALINOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against certified reference standard. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (S)- and (R)-enantiomers on chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents partitioned into headspace and quantified by GC-FID or GC-MS. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes sample in plasma and measures element-specific emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates anions on ion-exchange column; chloride quantified via conductivity response. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Specific Optical Rotation | [alpha]D Measurement using Polarimeter | Measures rotation of plane-polarized light at 589 nm; correlates with enantiomeric composition and concentration. |
| Appearance | Visual Inspection against Water-White Standard | Assesses clarity and color by comparison to specified reference under controlled lighting. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in aqueous dilution. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Evaporates sample at controlled temperature; residue weight determined by difference before/after drying. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase column and UV absorbance. |
