Manufacturing Quality Control of D-2-Bromophenylalanine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-220 nm based on peak area comparison against reference standard. |
| Enantiomeric Purity | Chiral HPLC | Resolves D- and L-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) using flame ionization detection. |
| Heavy Metals | ICP-MS | Detects trace metal impurities (e.g., Pb, Cd, Ni) via mass spectrometric quantification after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration of sample in presence of sulfuric acid. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light to confirm chiral integrity and concentration. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed particles to report D10, D50, D90 values based on light scattering pattern. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., de-brominated, racemized, or hydrolyzed analogs) using gradient elution. |
| Microbial Contamination | Membrane Filtration | Detects aerobic bacteria and fungi by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
