Manufacturing Quality Control of 4-Methyltetrahydro-2H-pyran-4-ol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals | ICP-OES | Quantifies trace metal elements (e.g., Pb, Cd, Hg, As) based on element-specific atomic emission intensities. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound in solution using plane-polarized light. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness against platinum-cobalt standard scale using 455 nm absorbance or matched glass standards. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at specified temperature using total internal reflection principle. |
| Density | Digital Density Meter | Measures mass per unit volume via oscillating U-tube principle with temperature control. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by analyzing equilibrium vapor phase above sample. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities using reversed-phase column and UV absorbance at 210 nm. |
