Manufacturing Quality Control of DL-3-Amino-3-(2-naphthyl)propionic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 220–254 nm, comparing peak area against a certified reference standard. |
| Chiral Purity (Enantiomeric Excess) | Chiral HPLC | Separation of DL-diastereomers on a chiral stationary phase, with UV detection to calculate enantiomeric excess based on peak area ratio. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) per ICH Q3C guidelines. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry for trace-level detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Incineration at 750 °C followed by weighing of non-volatile inorganic residue to assess inorganic impurities. |
| Related Substances | HPLC-UV (Forced Degradation Study) | Stability-indicating method using gradient HPLC-UV to separate and quantify structurally related impurities (e.g., decarboxylated, oxidized, or hydrolyzed derivatives). |
| pH (1% w/v aqueous solution) | pH Potentiometry | Measurement using calibrated pH electrode in aqueous suspension to assess acid-base behavior and potential salt formation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering to determine D10, D50, D90 values per USP <429>. |
