Manufacturing Quality Control of 3-Hydroxyhexanoic Acid Methyl Ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing in a muffle furnace. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities (e.g., Pb, Cd, As) by measuring absorption of characteristic wavelengths of light by ground-state atoms in a flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation of chloride ions as silver chloride followed by endpoint detection using a silver ion-selective electrode. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color intensity against platinum-cobalt standard solutions at 455 nm wavelength. |
| Refractive Index | Refractometry | Measurement of light bending angle at the air-sample interface using a calibrated Abbe refractometer at specified temperature. |
| Specific Gravity | Pycnometry | Determination of density ratio relative to water using a calibrated glass pycnometer at 20 degrees C. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities (e.g., methanol, hexane) quantified via equilibrium vapor phase analysis prior to GC separation. |
| Optical Rotation | Polarimetry | Measurement of angular rotation of plane-polarized light caused by chiral molecules in solution using a sodium D-line source. |
| Non-Volatile Residue | Evaporation and Gravimetry | Weighing of residue remaining after complete evaporation of a fixed sample volume under controlled heating and vacuum conditions. |
