Manufacturing Quality Control of 3-MERCAPTO-1-PROPANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-mercapto-1-propanol 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-based redox reaction in anhydrous methanol/pyridine medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines total acidic impurities by titration with standardized sodium hydroxide using phenolphthalein or potentiometric endpoint. |
| Thiols Content | Iodometric Back-Titration | Oxidizes free thiol groups with excess iodine; unreacted iodine is titrated with sodium thiosulfate to quantify -SH groups. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates color intensity by comparing sample against platinum-cobalt standard solutions at 455 nm or visually in Nessler tubes. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Measures bending of light at air-sample interface to determine refractive index at specified temperature (e.g., 20 C). |
| Residue on Ignition | Gravimetric Analysis | Heats sample to 500-600 C, then weighs non-volatile residue remaining after organic volatilization and decomposition. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelength for lead. |
| Sulfur Compounds (e.g., disulfides) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates and identifies sulfur-containing impurities (e.g., bis(3-hydroxypropyl) disulfide) via retention time and mass spectral matching. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporates fixed volume under controlled conditions, dries residue at 105 C, and weighs residual solids. |
| Odor Impurities | Gas Chromatography-Olfactometry (GC-O) or Comparative Sensory Panel | Detects and characterizes volatile odor-active compounds by coupling GC separation with human sensory evaluation at effluent port. |
