Manufacturing Quality Control of (R)-(-)-1,3-Butanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies (R)-(-)-1,3-butanediol by retention time and peak area against a certified reference standard. |
| Optical Rotation | [a]D Measurement using Polarimetry | Measures specific rotation at 20 C and 589 nm to confirm enantiomeric identity and purity. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on iodine consumption in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Titrates acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to platinum-cobalt standard solutions using APHA scale. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using Abbe refractometer at sodium D line. |
| Heavy Metals (as Pb) | ICP-OES after Acid Digestion | Quantifies total heavy metals following microwave-assisted nitric acid digestion and plasma emission detection. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile organic impurities (e.g., ethanol, acetone) by equilibrium headspace sampling and GC-FID analysis. |
| Related Substances | Chiral Gas Chromatography (cGC) | Resolves and quantifies enantiomeric and structural impurities using chiral stationary phase and FID detection. |
