Manufacturing Quality Control of D-4,4'-BIPHENYLALANINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by HPLC separation and UV absorption relative to the main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibration standards. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by plasma ionization followed by mass spectrometric detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Content | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity based on crystalline behavior. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering from a dispersed sample. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines acidity/basicity of a saturated aqueous suspension using a calibrated pH electrode and reference electrode. |
