Manufacturing Quality Control of 2H-PYRAN-3(4H)-ONE, DIHYDRO-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation on capillary column and flame ionization detection relative to external standard. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration based on iodine consumption in stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic impurities remaining after combustion at 700–800 °C. |
| Heavy Metals (as Pb) | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Multi-element quantification via atomic emission from plasma-excited atoms in digested sample. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities using standardized sodium hydroxide solution. |
| Color (APHA) | Visual comparison or spectrophotometric measurement at 430 nm | Compares sample absorbance at 430 nm against platinum-cobalt standard scale. |
| Refractive Index | Refractometry at 20 °C | Measures bending of light through liquid sample to assess purity and composition consistency. |
| Specific Optical Rotation | Polarimetry at 20 °C and sodium D-line (589 nm) | Determines enantiomeric excess or chiral impurity presence via rotation of plane-polarized light. |
| Residual Solvents (e.g., THF, MeOH) | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents by equilibrium vapor-phase analysis above sample. |
| Related Substances (Impurities) | GC-MS or HPLC with UV detection | Separates and identifies structurally related compounds using retention time and spectral matching. |
| Density at 20 °C | Digital densitometry | Measures mass per unit volume using oscillating U-tube principle for batch consistency control. |
