Manufacturing Quality Control of (-)-D-PYROGLUTAMIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm, based on peak area comparison against reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Measures enantiomeric purity by separation on a chiral stationary phase and UV detection, calculating ee from peak area ratio of (R) and (S) enantiomers. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically to generate endpoint current or volume change. |
| Heavy Metals | ICP-MS | Quantifies trace metals (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry for multi-element detection at sub-ppq levels. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., hydrolysis products, isomers) via gradient HPLC-UV with system suitability and threshold reporting. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light in a polarimeter to confirm chiral integrity and batch-to-batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation of meniscus collapse. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C followed by precise weighing of residual residue. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of a saturated aqueous suspension using calibrated pH electrode and meter. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser light and Mie theory calculation. |
