Manufacturing Quality Control of (S)-(-)-2-Methyl-1-butanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative separation and detection of S-(-)-2-methyl-1-butanol using a chiral or non-chiral column with flame ionization detection. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separation of enantiomers on a chiral stationary phase; ee calculated from peak area ratio of S-enantiomer vs R-enantiomer. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on iodine consumption in a reaction specific to water. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH solution using phenolphthalein or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile residue after controlled heating at 700-800 C in a platinum crucible. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantification of metals (e.g., Pb, Cd, Hg, As) by atomic absorption of characteristic wavelengths in air-acetylene flame. |
| Chloride Content | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions after sample dissolution and filtration. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity against APHA platinum-cobalt standard scale using 10 mm pathlength cell. |
| Density | Digital Density Meter | Determination of mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using Abbe refractometer at controlled temperature. |
| Non-Volatile Residue | Evaporation and Gravimetry | Weighing residue remaining after gentle evaporation of a defined sample volume under nitrogen stream and drying. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Detection and semi-quantitative identification of volatile organic impurities via retention time and mass spectral matching. |
