Manufacturing Quality Control of (R,R)-2,3-Butanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies main component using retention time and peak area against calibrated standard. |
| Optical Rotation | [alpha]D Measurement | Measures rotation of plane-polarized light to confirm chiral purity and enantiomeric excess. |
| Water Content | Karl Fischer Titration | Electrochemical titration quantifying water via iodine-sulfur dioxide reaction in methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by atomic absorption at element-specific wavelengths. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Color | APHA Color Scale Comparison | Compares sample color visually or spectrophotometrically against platinum-cobalt standards. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at 20/20 deg C using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 deg C to assess purity and concentration. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling organic impurities by GC analysis of vapor phase above heated sample. |
| Residual Solvents | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies common process solvents (e.g., methanol, acetone) using mass spectral libraries. |
