Manufacturing Quality Control of PROPARGYL METHANESULFONATE ESTER, 95
| 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 stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines total acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after drying. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample to infer purity and concentration. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Quantifies weight loss upon controlled heating to assess volatile impurities and thermal stability. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related compounds using reverse-phase column and UV absorbance detection. |
