Manufacturing Quality Control of (R)-(-)-3-HYDROXY-2-METHYLPROPIONIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation of enantiomers on a chiral stationary phase, with quantification based on relative peak areas of (-)- and (+)-enantiomer peaks. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantification based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified via calibration curve. |
| Sulfate Impurity | Ion Chromatography | Same principle as chloride; sulfate eluted and detected by conductivity after suppression. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities using gradient HPLC-UV, with identification by retention time and relative response. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually or automatically using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passed through a solution; specific rotation calculated from concentration, path length, and observed rotation. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile residue remaining after high-temperature ashing at 700-800 C, expressed as percentage of original sample weight. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity using calibrated glass electrode and pH meter in a standardized aqueous suspension. |
