Manufacturing Quality Control of 3-(2-Naphthyl)-D-alanine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~220–280 nm, comparing peak area against a certified reference standard. |
| Optical Rotation | [α]D | Measurement of specific rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm enantiomeric identity and purity. |
| Residual Solvents | GC-FID | Qualitative and quantitative analysis of volatile organic solvents (e.g., methanol, ethyl acetate, toluene) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Ultra-trace quantification of toxic elements (Pb, Cd, Hg, As, Ni) after acid digestion, based on elemental mass spectrometry detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric electrochemical reaction. |
| Related Substances (Impurities) | HPLC-UV/DAD | Separation and detection of structurally related impurities (e.g., starting materials, diastereomers, degradation products) using gradient HPLC with diode-array detection. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration (500–600 °C) followed by precise weighing of residual residue. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated pH electrode in a saturated or near-saturated aqueous suspension to assess acid-base behavior. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine volumetric particle size distribution (D10, D50, D90). |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating and visual observation of meniscus collapse. |
| Chloride Content | Ion Chromatography (IC) | Quantification of chloride anion after sample dissolution and filtration, using suppressed conductivity detection with anion-exchange column. |
| Specific Optical Rotation Purity | Chiral HPLC | Enantioselective separation on chiral stationary phase (e.g., cellulose-based) to quantify % enantiomeric excess (ee) relative to D-3-(2-naphthyl)alanine reference. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial compendia (USP <61>, <62>). |
