Manufacturing Quality Control of 2-(TETRAHYDRO-2H-PYRAN-2-YLOXY)ETHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against a calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing to APHA color standards or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature to infer purity and concentration. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelengths. |
| Non-Volatile Residue | Gravimetric Analysis | Determines volatile loss by evaporation under controlled conditions followed by weighing of residue. |
| Aldehyde Impurities | Derivatization GC or HPLC | Converts aldehydes to stable derivatives (e.g., DNPH) for separation and quantification. |
| Ethanol Content (Residual Solvent) | Headspace Gas Chromatography (HS-GC) | Detects trace ethanol by equilibrium partitioning into headspace and GC-FID analysis. |
