Manufacturing Quality Control of 2-Mercapto-3-butanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-mercapto-3-butanol by separation and flame ionization detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Oxidizes organic sulfur to sulfate, then quantifies sulfate ions via suppressed conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to platinum-cobalt standards or measures absorbance at 455 nm against distilled water blank. |
| Specific Gravity | Digital Density Meter | Determines density ratio relative to water at 20/20 degC using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light at air-sample interface using calibrated Abbe refractometer at 20 degC. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies volatile odor-active impurities by retention time and mass spectral matching. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions after aqueous extraction and filtration using anion-exchange column. |
| Non-Volatile Residue | Evaporation and Gravimetry | Measures residue weight after evaporation of fixed sample volume to dryness at 105 degC under controlled conditions. |
