Manufacturing Quality Control of (R)-1,2-Butanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies (R)-1,2-butanediol by retention time and peak area against a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (chiral-GC) | Separates (R)- and (S)-enantiomers using a chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration (coulometric or volumetric) | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing of sample at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using conductivity detection (IC) or silver nitrate titration (potentiometric). |
| Color (APHA) | Visual Comparison or Spectrophotometry (430 nm) | Compares sample color to APHA platinum-cobalt standards or measures absorbance at 430 nm. |
| Specific Optical Rotation | [a]D Measurement using Polarimeter | Determines enantiomeric identity and purity by measuring rotation of plane-polarized light at 589 nm. |
| Refractive Index | Refractometry | Measures bending of light at 20 C using sodium D-line to assess purity and concentration. |
| Distillation Range | Simple Distillation with Thermometer | Determines boiling range under specified pressure to detect volatile impurities or solvents. |
| Residual Solvents (e.g., MeOH, EtOH, Acetone) | Headspace Gas Chromatography (HS-GC) | Quantifies low-boiling organic solvents by GC analysis of vapor phase above heated sample. |
