Manufacturing Quality Control of 3-Mercapto-2-butanol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after controlled high-temperature ashing of sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance at characteristic wavelength for lead. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Total sulfur converted to sulfate ions, then separated and quantified by conductivity detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer at 20 C. |
| Boiling Point Range | Distillation (Micro or Semi-micro) | Observation of temperature range over which distillate is collected under reduced pressure (e.g., 10 mmHg). |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity against platinum-cobalt standard solutions in the visible range (455 nm). |
| Odor Threshold (Qualitative) | Sensory Evaluation by Trained Panel | Organoleptic assessment to detect presence of off-odor impurities exceeding acceptable sensory threshold. |
| Residual Solvents (e.g., Methanol, Ethyl Acetate) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvents partitioned into headspace, injected into GC, and quantified against calibration standards. |
