Manufacturing Quality Control of (+)-ETHYL D-LACTATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Lactic Acid Ethyl Ester Content) | Gas Chromatography (GC) with FID detection | Separation and quantification based on retention time and peak area against calibrated standard. |
| Optical Rotation | [a]D Measurement using Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral D-lactate ester in solution. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison to platinum-cobalt standards or absorbance measurement at specified wavelength to assess yellowness. |
| Density at 20 degC | Digital Density Meter or Pycnometer | Measurement of mass per unit volume at controlled temperature using oscillating U-tube or calibrated glass vessel. |
| Refractive Index at 20 degC | Refractometry | Determines ratio of speed of light in air vs. sample using prism-based instrument at specified temperature. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample volume to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and chelation, based on absorption of characteristic atomic line radiation. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separation and detection of Cl- ions via conductivity or endpoint detection using silver nitrate titrant. |
| Esters Profile (Ethyl Acetate, Ethanol, etc.) | Gas Chromatography (GC) with FID | Simultaneous separation and quantification of volatile co-solvents and related esters using capillary column. |
| Non-Volatile Residue | Gravimetric Analysis | Heating of sample to remove volatiles followed by weighing of residual solids after cooling in desiccator. |
