Manufacturing Quality Control of D-1-Naphthylalanine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at ~220–280 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Resolves D- and L-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) using capillary GC with flame ionization detection. |
| Heavy Metals (as Pb) | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Hg, Ni) after acid digestion via inductively coupled plasma mass spectrometry. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500–600 °C) and precise weighing. |
| Related Substances | HPLC-UV (Forced Degradation) | Identifies and quantifies structurally related impurities (e.g., deaminated, oxidized, or hydrolyzed derivatives) using stability-indicating HPLC method. |
| Optical Rotation | [α]D Measurement | Measures specific rotation at 589 nm (Na-D line) using a polarimeter to confirm chiral integrity and identity. |
| pH (1% aqueous suspension) | pH Meter | Determines acidity/basicity of a saturated aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersion particle size distribution via Mie scattering theory applied to laser diffraction patterns. |
