Manufacturing Quality Control of 4-Mercapto-4-methylpentan-2-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction in methanol/pyridine medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by matching sample color to APHA platinum-cobalt scale or measuring absorbance at specified wavelength. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from oscillation period of a filled U-shaped tube calibrated with water and air. |
| Refractive Index at 20 C | Abbe Refractometer | Measures bending of light passing through sample to determine refractive index relative to sodium D-line (589 nm). |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame/graphite furnace and measuring absorption at characteristic wavelengths. |
| Sulfur Content (Total) | Combustion IC (Ion Chromatography after Combustion) | Oxidizes organic sulfur to sulfate, then detects sulfate anion concentration via conductivity detection. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration using silver/silver chloride electrode for endpoint determination. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Separates and quantifies volatile solvents (e.g., acetone, methanol) using headspace sampling and GC-FID. |
| Odor Profile | Gas Chromatography-Olfactometry (GC-O) or Sensory Panel | Identifies and semi-quantifies odor-active compounds via human detection at GC effluent or standardized sensory evaluation. |
