Manufacturing Quality Control of ETHYL (R)-(-)-MANDELATE
| 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. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separation of (R)- and (S)-enantiomers on a chiral stationary phase; ee calculated from relative peak areas. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents partitioned into headspace above sample, then quantified by GC-FID against calibration standards. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma; emission intensity measured at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anionic separation on ion-exchange column; chloride quantified by conductivity response relative to calibration curve. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Neutralization of free carboxylic acid groups with standardized sodium hydroxide solution; endpoint detected potentiometrically. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color intensity against platinum-cobalt standard solutions using visual match or absorbance at 455 nm. |
| Specific Optical Rotation | [a]D Measurement (Polarimetry) | Measurement of rotation angle of plane-polarized light passing through a solution; related to enantiomeric composition and concentration. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700-800 C) | Incineration of sample to remove organic matter; residual inorganic ash weighed after cooling in desiccator. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation of impurities and degradation products on reversed-phase column; detection at 210–230 nm and quantification versus reference standards. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity determined using calibrated glass electrode and reference electrode in aqueous suspension or saturated solution. |
