Manufacturing Quality Control of Ethyl (S)-3-hydroxybutyrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation and flame ionization detection relative to internal/external standard. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Resolves (R)- and (S)-enantiomers on chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles extracted into headspace, injected into GC for quantification against calibration standards. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color intensity to platinum-cobalt standard solutions at 455 nm. |
| Specific Optical Rotation | [a]D Measurement (Polarimetry) | Measures rotation of plane-polarized light at 589 nm; indicates chiral purity and identity. |
| Heavy Metals (as Pb) | ICP-OES after Acid Digestion | Sample digested in nitric acid; metals quantified by atomic emission intensity at characteristic wavelengths. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after high-temperature ashing. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using conductivity detection after suppressed eluent. |
| Appearance | Visual Inspection | Assessment of clarity and absence of visible particulates or immiscible phases in a transparent container under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
