Manufacturing Quality Control of Ethyl S-4-chloro-3-hydroxybutyrate
| 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 using a non-polar capillary column. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separation of R- and S-enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents quantified by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride anions using an anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element trace metal quantification after acid digestion via plasma ionization and mass-selective detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and UV absorbance at 210 nm. |
| Optical Rotation | [a]D Measurement using Polarimeter | Determination of specific rotation at 589 nm (Na D-line) in solution, proportional to enantiomeric composition. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample ignited at 700-750 C after sulfuric acid treatment; residual inorganic ash weighed. |
| Appearance | Visual Inspection in Glass Vial under Controlled Lighting | Assessment of physical state, color, and clarity against established visual standards under daylight-equivalent illumination. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
