Manufacturing Quality Control of 3-Bromo-L-tyrosine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 280 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., bromination by-products, dehalogenated analogs) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) at sub-ppb levels using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of a defined aqueous suspension using calibrated glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by measuring temperature range over which solid transitions to liquid. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms using membrane filtration followed by incubation on TSA and SDA agar plates. |
